small portable gold process plant
This arrangement and flowsheet of a Mini Portable Gold Processing Plant permits several mineral separations by flotation and provides for the possible recovery of other minerals by gravity concentration. The flowsheet is ideal for a pilot-plant in field testing of ores to determine the economic feasibility of an ore deposit prior to the installation of a larger plant or for processing ore during the development stages of a mining property.
The arrangement shown here features the economy type rubber-lined Grinding Mill. This mill is roller-mounted with V-belt drive around the mill shell, driven from motor-connected gear reducer. Material discharged from the grindingmill is sized through a spiral screen ahead of a Cyclone Classifier. The flotation cells handling initial feed are equipped with patented discharge cones for return and recovery of a heavy mineral fraction by a jig.Tailings from the flotation machines are fed to a #6 Concentrating Table to assure gravity recovery of any valuable mineral not amenable to flotation. Pan Filters are provided to de-water concentrates.
One of the most serious problems confronting the mining industry today is how to profitably begin the small scale milling of ores from mines where insufficient ore has been developed to warrant an expensive mill installation, but where a large plant might be needed later. The same question arises in connection with the economical working of numerous small but relatively high grade ore deposits.
Portable Mills, and in particular, Truck Mills, are a most practical solution to this problem. For a relatively small investment a complete and efficient mill can be brought to the mine and speedily put into operation. When the high grade deposit has been worked or the formerly promising operation no longer fulfills the operators expectations, the mill may be transported as a complete unit to another location.
In the Truck Mill the portability has been carried out to the highest degree. All of the units are carried on a truck or semi-trailer, which serves as the operating floor for most of the units. Power for the entire milling unit is usually supplied with either a Diesel or gasoline driven electric generating set, but a belt driven mill can be supplied.

blanket gold mine - caledonia mining corporation plc
The current Blanket mining area has eight ore shoots in the producing section of the mine. The majority of the mine production is sourced at present from the AR Main and AR South ore bodies with a lesser contribution from the Blanket, Eroica and Lima reefs.
Significant early production milestones were: in 1965 Falconbridge acquired the property and increased gold production to an average of approximately 45 kg per month; in 1993 Kinross took over the property and built an enlarged Carbon-in-Leach (CIL) plant with capacity of approximately 3,800 tonnes per day (tpd) to treat an old tailings dump together with the run-of-mine ore.
On April 1, 2006 a wholly-owned subsidiary of Caledonia Mining Corporation completed the purchase of the Blanket Mine from Kinross. Caledonia has allowed Blanket to make considerable capital investments in its underground, surface and township facilities. These investments culminated in the commissioning of the No 4 Shaft Expansion Project at the end of September 2010 whichincreased Blankets hoisting capacity from the No. 4 Shaft from 500 tonnes per day to 3,000 tonnes per day.
The current Blanket mining area has eight ore shoots in the producing section of the mine. The majority of the mine production is sourced at present from the AR Main and AR South ore bodies with a lesser contribution from the Blanket, Eroica and Lima reefs. AR Main and AR South are massive ore bodies up to 30 m wide and are ideally suited to the long-hole open stope mining method, while the remainder of the Blanket ore bodies are tabular and better suited to underhand stoping methods.
Following the successful commissioning of the No. 4 Shaft Expansion Project in September 2010, the underground workings have increased production to approximately 1,200tonnes of ore per day using both long-hole open stoping and underhand stoping methods. Broken ore is trammed along the 22 Level rail system by battery locomotives and the ore cars trains are self-tipped onto one of three grizzlys above the ore bins which are located between 22 Level and the 765m level crushing station. The minus 300 mm rock held in three underground storage bins, Payable ore and waste ore are held in separate storage bins and handled accordingly. Ore is gravity fed from these ore bins onto the 765m Level crushing station conveyor which discharges the ore onto a vibrating grizzly feeder which discharges the oversize into a 30 x 20 Telsmith jaw crusher.
The underground crushing station ensures that all the run-of-mine ore is reduced to minus 150 mm in size as this provides for the optimisation and greater efficiency of the automated skip loading and hoisting operations. This allows mining and hoisting activity to continue without interruption.
Blanket No. 4 Shaft has been equipped with the first automated loading system in Zimbabwe which sequentially fills the two six tonne ore skips which are hoisted from the 789m level to surface. The use of this state of the art automation reduces the risk of ore loading accidents and injuries, reduces manpower costs, minimises spillage, reduces skip loading times, increases hoisting capacity, ensures precise ore tonnage accountability, and enhances winder efficiency while lowering loading and hoisting costs.
The double compartment No. 4 Shaft is Blankets main shaft for hoisting ore to surface from the loading stations at 510m and 789m below surface, and it has a proven hoisting capacity of 110 tonnes per hour from 789m. The Jethro and Eroica Shafts and the No.5 and No.6 Winzes are used for transporting personnel and materials underground, and the No.2 and Lima Shafts are also used for hoisting ore to surface.
The entire underground and surface operations of the Blanket mine, except for the Lima Shaft, including the surface compressors and the No 4 Shaft Winder can be operated by the 10,000kVA standby diesel powered generating sets which were installed and commissioned in May 2011.
This standby generating station ensures that all mining and metallurgical operations continue notwithstanding any interruptions to the electrical power supply from the grid. The level of interruptions to Blankets power supply has diminished considerably following the agreement of an un-interrupted power a supply agreement between Blanket and ZESA. In the year to 31 December 2012, the standby generators were used for a total of 108 hours (2011, 121 hours).
The Blanket Mine is situated in the Gwanda Greenstone Belt, a typical Archaean greenstone-hosted gold deposit. The deposit is situated on the northwest limb of the Gwanda Greenstone Belt along strike from several other prominent gold deposits. Blanket is the largest producing mine in a belt which at one time had 268 operating mines.
The Gwanda Greenstone Belt extends 80 km in an east-west direction and consists predominantly of basaltic rocks (greenstones) with minor felsic and ultramafic units. The belt has been intensely sheared and intruded by granites resulting in complex deformation structures and vertically dipping strata. The shape of the gold ore bodies is controlled by these structures, resulting in their near vertical orientation.
Near vertical shear zones are developed throughout the belt and are the loci of most of the small mines that have been discovered in the area. Most of Blankets prospects are of this type. Many of these now defunct small mines were shallow, had historically high recovered gold grades and closed towards the end of the 1960s when the gold price was low and the mining and metallurgical techniques available at that time were such that the mines became un-economic. The area has a long history of gold production and remains highly prospective and must therefore be regarded as an attractive exploration area as it has never been subjected to modern exploration techniques.
Active mining at the Blanket mine takes place over a 3 km strike that includes 8 discrete ore shoots. Fig NN provides a north-south vertical projection of the various Blanket ore shoots. Mineralisation occurs in near vertical shoots aligned along an approximately north-south axis. The ore shoots vary in shape from the tabular to lensoidal quartz reefs to the massive to pipe-like disseminated sulphide reefs (DSR).
Gold mineralisation occurred as a result of the reaction between rising hot fluids and the iron rich minerals in the shear zones. The reaction involved the formation of sulphide minerals, predominantly arsenopyrite, as the sulphur in solution reacted with iron in the rocks. Gold, which was also transported by the fluids, became attached to the arsenopyrite to form the gold ore. These reaction zones are located within the more ductile tensional high strain areas of the shear zone.
Blanket Mine is part of the group of mines that make up the North Western Mining Camp otherwise also called the Sabiwa group of mines. What is today referred to as Blanket Mine is a cluster of mines extending from Jethro in the south, through Blanket itself, Feudal, AR South, AR Main, Sheet, Eroica and Lima in the north. These ore shoots occur in the Blanket shear zone, a low angle transgressive shear characterised by the presence of biotite relative to the massive amphibolites forming the country rocks.
A regional sub horizontal dolerite sill intruded the above sequence and is emplaced about 500 meters below surface. The sill does not cause a significant displacement and although it truncates all the ore shoots, the mineralised shoots continue undisturbed below the sill.
Since the rock units of the Gwanda Greenstone Belt are tilted on their side and strike north-south in the vicinity of Blanket Mine, the stratigraphic sequence is exposed from the oldest in the east to the youngest in the west. The Felsic unit consisting of quartzite and sericite-quartz schists forms the base of the stratigraphy. No gold deposits have been recorded in this unit. Overlying this unit to the west is the Ultramafic-Mafic unit interlayered with banded iron formations. Gold occurs in this unit at Vubachikwe mine, which is adjacent to Blanket, where the deposits are confined to steeply dipping folds in the banded iron formation layers. The Ultramafic-Mafic unit is in turn overlain to the west by the Mafic unit, a thick sequence of tholeiitic and pillow basalts. Within the Mafic unit a prominent shear zone up to 50 meterswide runs the length of the property and is the locus of all ore bodies on the Blanket property. The sequence is completed by an Andesitic unit which caps the stratigraphic sequence.
The first type is the disseminated sulphide replacement type which comprises the bulk of the ore shoots. Typically these zones have a silicified core with fine sprays of disseminated arsenopyrite hosting the best grades. Disseminated sulphide replacement ore bodies range up to 50m in width with a strike between 60m and 90m. Free-milling gold constitutes up to 50% of the total metal content with the remainder occluded within the arsenopyrite.
Quartz-filled shear zones form the second type of mineralisation. Two quartz shears are mined at Blanket Mine, the Blanket Quartz Reef and the Eroica Reef. These reefs tend to have long strikes but are not uniformly mineralized although continuous pay shoots of over 100 m on strike are not uncommon. The Quartz Reef at Blanket has a surface strike of some 500 m, but economic mineralisation is restricted to three 90 m shoots which were defined on surface by the early workers. Grade fluctuations are more extreme in the quartz reefs than in the disseminated type reefs but on average these shears have higher grades and are used as a sweetener of ore to the mill.
Caledonias Board and Management have completed a review of alternative expansion and diversification plans for Caledonia. Both the Board and Management have also addressed the revised production projections for the Blanket Mine and the possible benefits of diversifying Caledonias production base. Caledonia has concluded the best returns on investment remain at the Blanket Mine in Zimbabwe, which continues to be cash generative in the current adverse market conditions and also offers significant investment returns that exceed alternative investment opportunities.
The objectives of the Revised Plan are to improve the underground infrastructure and logistics and allow an efficient and sustainable production build-up. The infrastructure improvements will include the continuation of the No. 6 Winze, the development of a Tramming Loop and the sinking of a new 6-meter diameter Central Shaft from surface to 1,080 meters.
The increased investment pursuant to the Revised Plan is expected to give rise to production from inferred resources of approximately 70-75,000 ounces in 2021, this being in addition to projected production in 2021 from proven and probable mineral reserves of approximately 6,000 ounces. The Revised Plan is also expected to improve Blankets long term operational efficiency, flexibility and sustainability.
The skips automatically tip ore hoisted to surface into the Shaft Bins on the No4 Shaft headgear. Ore is gravity fed from the Shaft Bins onto the No1 belt which conveys the ore over the automated belt scale and to vibrating screens and 1424 Telsmith jaw crushers. This crushing circuit reduces the ore to minus 50 mm and it is then deposited by the No 2 belt stockpile conveyor onto the coarse ore stockpile which has a live capacity of approximately 2,000 tonnes of material. Ore from the coarse ore stockpile is then fed onto the triple-deck vibrating screen with the oversize being crushed to minus 12 mm by one of two 38H Telsmith Gyrasphere crushers. The 12mm ore is then fed into the 600 tonne Mill Bin which feeds the two (of the three installed) 1.8 x 3.6 m rod mills where it is milled down to approximately 70% passing 75 microns, before being passed through two 30 inch continuous Knelson Concentrators where approximately 49% of total gold production is recovered. The Knelson Concentrator tails are pumped through cyclones and into a 3.66 x 4.9 m x 750kW (1,000 HP) regrind ball mill. As part of the No.4 Shaft Expansion Project, the capacity of the secondary crushers was increased to over 2,000 tpd and the capacity of the rod mills was increased to 1,800 tpd. The slurry from the regrind mill is pumped into a carbon in leach (CIL) plant consisting of eight, 600 cubic meter leach tanks equipped with 45 kW agitators where leaching at 50% solids and simultaneous adsorption of dissolved gold onto activated carbon takes place. The CIL plant has a nameplate capacity of 3,800 tonnes of milled ore per day. Elution of the gold from the loaded carbon and electro winning is done on site. Gold is deposited onto steel wool cathodes, the loaded cathodes are acid-digested and the resultant gold solids are smelted in an induction furnace to produce gold bullion of approximately 90% purity, after which the bullion is sold as required by Zimbabwean law to Fidelity Printers and Refiners (Fidelity) in Harare which undertakes final refining and sale. The proceeds of sale (i.e. 98.5% of the value of the gold contained before payment of any royalty) are paid directly into Blankets foreign currency account with its commercial bank in Zimbabwe within 7 days of receipt of the gold by Fidelity.
Overall gold recovery rates have been increased from 85% at the time of acquisition by Caledonia to over 94% as a result of the re-design of more efficient CIL agitators and the installation of an automated liquid sodium cyanide facility which allows for multiple stage cyanide dosing and monitoring of the CIL. The PSA (Pressure Swing Adsorption) Oxygen Generator has been re-commissioned and the controlled sparging of oxygen into the CIL has resulted in an increase in leach recoveries to approximately 94%.
No. 1 Conveyor feeding the two Primary Jaw Crushers. Tailings from the CIL circuit contain less than 30 ppm of cyanide, and are pumped to one of two tailings dams which are operated and maintained by Fraser Alexander, and are inspected and monitored daily by Blanket.
Historical operating statistics for the Blanket Mine are available in Caledonias MD&A, which can be found in the Investor section of Caledonias website. Blankets historic financial performance up to February 2009 was accounted for in Zimbabwean dollars until 2009. Due to the extreme hyper-inflationary environment which prevailed in Zimbabwe until early 2009 and the resultant devaluation of the Zimbabwean dollar, Blankets stated historic financial statements are unhelpful for the purposes of evaluating Blankets historic financial performance. The Zimbabwean dollar was abolished in February 2009 and all financial transactions in Zimbabwe now take place using other currencies, including the US Dollar, the South African Rand and the Botswana Pula. With effect from 1 January 2009, Blanket has prepared its accounts in US Dollars.
The proposed Central Shaft will be a 3,000 tonne per day, 6-meter diameter, 4-compartment shaft that will transport men, equipment and material from surface to 1,080 meters below surface. The shaft will be located between the AR Main and AR South ore bodies, in the middle of Blankets mining area. Construction on the shaft is expected to commence in July 2015, following completion of the Tramming Loop. The capital cost of the Central Shaft is expected to be approximately US$23 million. The shaft will be sunk in two simultaneous phases: from surface from 750m below surface and is expected to be completed in July 2017. Once complete, the Central Shaft will provide access for horizontal development in two directions on two levels below 750m.
The increased investment pursuant to the Revised Plan is expected to give rise to production from inferred resources of approximately 70-75,000 ounces in 2021, this being in addition to projected production in 2021 from proven and probable mineral reserves of approximately 6,000 ounces. The Revised Plan is also expected to improve Blankets long term operational efficiency, flexibility and sustainability.
The Revised Plan includes a revised life of mine plan for the Blanket Mine (the LOM Plan) in terms of which it is anticipated that the approximate production from existing proven and probable mineral reserves above 750 m level will be as set out below.
Central Shaft and the associated capacity improvements in the Blanket Processing Plant are expected to enable an increase in gold production at Blanket to 75,000 ounces by 2021 and 80,000 ounces from 2022 onwards. Improved access to Inferred Mineral Resources at depth is expected to enable the maintenance of this 80,000 ounce per year production rate until approximately 2034.
The new Central Shaft and the deepening of No 6 winze will provide access to the current inferred mineral resources below 750 meters and allow for further exploration, development and mining in these sections along the known Blanket strike, which is approximately 3 kilometers in length. The PEA has been prepared in respect of the inferred mineral resources below 750 meters. Based on the PEA, additional approximate production from current inferred mineral resources (excluding the projected production set out above) may be achieved in the following indicative ranges:
The PEA is preliminary in nature and includes inferred mineral resources that are considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as mineral reserves. There is no certainty that the PEA will be realised. Diamond drilling and development will continue with the objective of increasing confidence in order to upgrade the categorization of the resources.
The LOM Plan and the PEA have been reviewed by Minxcon Consulting, an independent mining consulting company. A technical report prepared in compliance with National Instrument 43-101 which summarizes the revised LOM Plan and the PEA will be filed on SEDAR before December 17, 2014. The most important assumptions on which the PEA is based include, a gold price of US$1,200 per ounce, achievement of the targeted production set out above and the accuracy of the projected capital costs.
It is also intended to continue exploration at two of Blankets satellite projects, Mascot and GG. No production forecasts are attributed to mining activity at either GG or Mascot at this stage as neither of these currently have defined NI43-101 mineral reserves or resources.
maaden awards $880m gold mining contract | arab news
The agreement was signed for Jac Rijk Al-Rushaid Contracting and Services Company to provide operational mining services at the gold mines. The range of services will include drilling, scaling, loading, hauling, re-handling, ore control, dewatering, crusher feed, and all related production activities at the mines.
Maaden on Sunday also announced the completion of the pre-operational stage at its third ammonia plant in Ras Al-Khair Industrial City. The $900 million project is expected to be completed in the fourth quarter of 2021 and will start operations in the first quarter of 2022, the Saudi Press Agency reported.
The ammonia plant is the first project as part of Maadens $6.4 billion Phosphate 3 expansion plan, which aims to add 3 million tonnes of phosphate fertilizer production capacity to Maadens portfolio. This will bring Maadens total production capacity of more than 9 million tonnes and make it one of the top three global phosphate fertilizer producers in the world.
Maaden CEO Abdul Aziz Al-Harbi said in a press statement: This is a tremendous milestone for our phosphate portfolio. The ammonia plant expansion will add over 1 million tonnes of ammonia production to reach 3.3 million tonnes, making Maaden one of the largest ammonia producers east of the Suez Canal.
The Kingdoms Ministry of Energy has estimated its untapped mineral resources to be worth about SR 5 trillion. Under Vision 2030, the government is aiming to triple the mining and metals sectors contribution to gross domestic product and create 200,000 jobs directly and indirectly by 2030.
Saudi Arabia has vast under-explored territories compared with other world-class mining countries. Maadens goal is to capitalize on that to become one of the worlds top mining companies, and we are making great strides in achieving this goal, Mosaed Al-Ohali, former CEO of Maaden, told Arab News in October 2020.
The increase in exploration spending is focused on brownfield drilling, assessment of potential greenfield targets and continued drilling at many prospective locations to maintain healthy ore reserves. We are working on two more gold mines that we expect to bring on stream around the middle of the decade, he added.
RIYADH:ACWA Power, the utility developer backed by Saudi Arabias Public Investment Fund (PIF), is planning to invest $16 billion in new projects around the world in 2021, ahead of plans for an initial public offering (IPO).
Early last year, CEO Paddy Padmanathan said the company planned to invest $10 billion in new projects in 2020. In light of the restrictions put in place by global governments as a result of the coronavirus (COVID-19) pandemic, some of these plans took longer to materialize.
The only challenge that we had on the new growth business is that some of the transactions where we were successful have taken anywhere between three to six months more in coming to what I would call the end of the development phase, which is the financial close and start of the construction, Rajit Nanda, ACWAs chief portfolio management and interim chief investment officer, told Arab News.
We did approximately $3.5 billion of projects during the course of 2020, taking them through to financial close, and during the course of 2021 we are targeting about $16 billion of projects under close, four of them have already closed actually, a couple of them closing in the next 30 days as we speak.
The investment officer said ACWA Powers main geographical focus is the Gulf Cooperation Council (GCC), with Saudi Arabia at the core of it, but it is also looking at opportunities in Africa and at markets in Central Asia and parts of Southeast Asia, such as Vietnam, Indonesia and Bangladesh.
At the end of last year, ACWA Power announced it will develop Azerbaijans first wind power development in collaboration with local entities, as part of joint energy projects with the Kingdom worth $300 million.
We already have very important positions in countries like Egypt and Morocco. But we are looking at a few other countries, like Senegal and Tunisia and so forth, in terms of our expansion objectives, Nanda explained.
Established in Riyadh in 2004, ACWA Power employs around 3,500 people and is currently active in 13 countries in the Middle East, Africa, Central Asia and Southeast Asia. Its portfolio includes 64 assets with an investment value of SR248 billion ($66 billion).
The company has gone through some very interesting dynamics in terms of evolution. One of them, which is a very important one, is the fact that the sovereign wealth fund of the Kingdom of Saudi Arabia is now a 50 percent important shareholder in ACWA Power, Nanda said.
Its association with PIF means the company has been able to win some major contracts related to the Kingdoms Vision 2030 megaprojects. One of the most prominent recent examples is the $6 billion hydrogen project, in partnership with NEOM and Air Products.
The project is now in its early stages, with completion expected by 2025. In an interview with Asharq News, the Chairman of ACWA Power Mohammad A. Abunayyan, said: NEOM city enjoys a strategic location for renewable energy, especially with wind and solar energy, which will enable the joint venture to convert renewable energy into green hydrogen with new technology for the first time. This project benefits not only NEOM but the whole world, as its green energy products will be exported everywhere.
This joint venture will produce 650 tons per day of carbon-free hydrogen and 1.2 million tons of green ammonia per year, reducing carbon dioxide emissions by the equivalent of 3 million tons per year.
Another major win in the Kingdom was the awarding of a contract from The Red Sea Development Company (TRSDC) to design, build, operate and transfer the Red Sea Projects utilities infrastructure, one of the Kingdoms flagship new tourism projects
This will be the regions first tourism destination powered solely by renewable energy. The contract includes the provision of renewable power, drinking water, wastewater treatment, solid waste management and district cooling for the 16 hotels, international airport and infrastructure that make up Phase 1 of the Red Sea Project.
Being in a capital-intensive business (such as) power generation and water, it is part of our business model to continuously evaluate the funding options that are available to us, Nanda said. We have established our connections with the debt capital markets. We have put ACWA Power in front of these high-quality investors and that chain of relationship is now established.
While Nanda would not give any further details on ACWA Powers long delayed IPO, the Capital Market Authority last week gave the green light for the listing of an 11.1 percent stake. The approval remains in place for six months, but chairman Abunayyan said in November he expected the IPO to happen by the end of 2021.
CHENNAI:Indian tycoon Mukesh Ambanis $10 billion entry into renewable energy could drive solar tariffs further to the ground and ignite bidding wars with fellow billionaire Gautam Adani, industry analysts say. Indias two richest men are vying to be at the forefront of Prime Minister Narendra Modis ambition to ramp up green energy capacity in the worlds second-most populous country more than fourfold to 450 gigawatts (GW) by 2030.
They have mostly avoided operating in each others space and the renewable energy push by Ambanis flagship Reliance Industries and the Adani group of companies will be the highest profile faceoff between them.
Ambani announced last month he will build 100 GW in solar energy capacity over the next nine years. He said his group would spend $10 billion over the next three years in building solar manufacturing units, a battery factory for energy storage, a fuel cell factory, and a unit to produce green hydrogen. Three days later, Adani announced that his green energy venture would add 5 GW every year this decade, from a current level of about 3.5 GW.
Analysts say there is sufficient space for multiple companies to grow as a part of Indias ambitious green energy target, but tariffs could fall further as companies try to outdo each other in aggressive bidding wars to win projects.
I would expect by 2030 that they (solar tariffs) will probably touch 1 rupee per kilowatt hour, said Tim Buckley, director of energy finance studies at the Institute of Energy Economics and Financial Analysis.
If both companies hit their targets, Reliances targeted solar capacity of 100 GW will be twice as large as Adanis, and the companies would together account for a third of all of Indias 2030 target.
RIYADH: The Saudi Arabian Investment Company (Sanabil Investments) on Wednesday announced that its parent company, the Public Investment Fund, had approved increasing its share capital by 50 percent to SR30 billion ($8 billion).
Sanabil has implemented its new strategy in 2019 to focus on venture capital, growth strategies and small buyouts, from early to more mature stages of the business life cycles, the company said in a press statement.
In February, Sanabil Investments entered into partnership with the Californian venture capital firm 500 Startups to launch an early stage accelerator program for startups in the Kingdom looking to expand across the Middle East and beyond.
The Sanabil 500 MENA Seed Accelerator Program consists of six programs run by 500 Startups over three years for a group of pre-seed and seed stage startups from across the MENA region. Up to 100 startups are expected to receive investment of up to $100,000.
From around 500 applications, 14 startups from the MENA region, including Saudi Arabia, the UAE, Egypt, Jordan, and Palestine, were chosen to present their companies to an audience of potential investors at a showcase on Wednesday.
RIYADH: Saudi employment officials have set minimum salaries for operations and maintenance roles under a broader localization push.
Senior managers working in public operations and maintenance are entitled to a minimum salary of SR9,000 ($2,399), the Ministry of Human Resources and Social Development said in a filing on Wednesday.
Pay rises according to years of experience with further details available in the Localization Guide for Operation and Maintenance Contracts in Public Entities.
The guide also sets minimum salaries for engineering and specialist levels at SR8,400, and SR7,000 for the supervisory level.
Such salary scales for different roles tie in with efforts by the government to reduce reliance on expatriates and get more Saudis into the workplace. Other Gulf states are involved in similar initiatives to boost local hiring as the regions non-oil economy gains in significance.
DUBAI: The worlds deepest swimming pool has opened in Dubai, featuring a sunken city that includes an apartment, garage and arcade.

These gold professionals are specifically in gold processing through various beneficiation technologies, for gold ore of different characteristics, such as flotation, cyanide leaching, gravity separation, etc., to achieve the processing plant of optimal and cost-efficient process designs.
Based on abundant experiences on gold mining project, Prominer helps clients to get higher yield & recovery rate with lower running cost and pays more attention on environmental protection. Prominer supplies customized solution for different types of gold ore. General processing technologies for gold ore are summarized as below:
For alluvial gold, also called sand gold, gravel gold, placer gold or river gold, gravity separation is suitable. This type of gold contains mainly free gold blended with the sand. Under this circumstance, the technology is to wash away the mud and sieve out the big size stone first with the trommel screen, and then using centrifugal concentrator, shaking table as well as gold carpet to separate the free gold from the stone sands.
CIL is mainly for processing the oxide type gold ore if the recovery rate is not high or much gold is still left by using otation and/ or gravity circuits. Slurry, containing uncovered gold from primary circuits, is pumped directly to the thickener to adjust the slurry density. Then it is pumped to leaching plant and dissolved in aerated sodium cyanide solution. The solubilized gold is simultaneously adsorbed directly into coarse granules of activated carbon, and it is called Carbon-In-Leaching process (CIL).
Heap leaching is always the first choice to process low grade ore easy to leaching. Based on the leaching test, the gold ore will be crushed to the determined particle size and then sent to the dump area. If the content of clay and solid is high, to improve the leaching efficiency, the agglomeration shall be considered. By using the cement, lime and cyanide solution, the small particles would be stuck to big lumps. It makes the cyanide solution much easier penetrating and heap more stable. After sufficient leaching, the pregnant solution will be pumped to the carbon adsorption column for catching the free gold. The barren liquid will be pumped to the cyanide solution pond for recycle usage.
The loaded carbon is treated at high temperature to elute the adsorbed gold into the solution once again. The gold-rich eluate is fed into an electrowinning circuit where gold and other metals are plated onto cathodes of steel wool. The loaded steel wool is pretreated by calcination before mixing with uxes and melting. Finally, the melt is poured into a cascade of molds where gold is separated from the slag to gold bullion.
