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.

As a very important traditional metal resource, copper has been developed widely and China is a very big market for copper. With decades experiences Prominer is professional in providing the technological solution for various types of copper mineral to achieve high recovery rate and yield. Besides, high quality of copper processing equipment can be sourced from Prominer.

There are mainly three types of copper ore: sulfide type copper ore, oxide type copper ore and mixed ore. Based on abundant experiences on copper mining project, Prominer supplies customized solution for different types of copper ore. General processing technologies for copper ore are summarized as below:

1. Flotation process are widely used for copper extraction. The ore pulp slurry is pumped to flotation cells for extracting. The flotation cells are divided into several parts: roughing, concentration and scavenging (the exact numbers of stages for each part should be decided by test work to reach the best recovery), and with the use of frothing agent and collecting agent, the copper concentrate will be collected. Normally there are one stage separation or multi stages separation for the technological process.

2. Leaching process for copper ore includes acid leaching and ammonia leaching. Leaching process is mainly for oxide copper that is very difficult to be extracted by flotation. Also for some copper ore it is combined by both oxide copper ore and sulfide copper ore, after processing test combined processing technologies can also be adopted to extract copper.

capricorn copper mine, queensland - mining technology | mining news and views updated daily

capricorn copper mine, queensland - mining technology | mining news and views updated daily

The Capricorn copper mine (formerly Mt Gordon and Gunpowder mines) is one of the largest copper mining projects being undertaken in Australia. The high-grade resource is expected to contain more than 900,000t of copper metal and is anticipated to produce 30 kilotonnes per annum (ktpa) of copper concentrate over its initial mine life of ten years.

The Capricorn Copper joint venture between Lighthouse Minerals (LHM) and EMR Capital (EMR) acquired the mine in October 2015 from Aditya Birla, a company based in India. The Queensland government granted Prescribed Project Status for the copper mine in April 2017.

The copper mine underwent a A$110m (approximately $81m) refurbishment and restart programme. The mine produced first copper concentrate in November 2017 and has produced 10,000 dry metric tonnes (dmt) of concentrate by 28 January 2018. The first concentrate shipment was made in February 2018.

Capricorn Copper has initiated restart execution studies (RES) to identify the prospects of restarting operations at the Capricorn copper mine. A restart and refurbishment project (RRP) has been established to estimate the capital costs and undertake readiness programmes required to restart mine operations.

The study concluded that the desired operational efficiencies could be achieved through the maintenance of existing facilities, replacement of outdated technology, expansion of existing production system, and construction of new equipment / facilities.

Located approximately 125km north-west of Mt Isa in north-west Queensland, the copper mine is hosted within the Western Fold Belt of the Mount Isa Inlier. The Inlier comprises early to middle Proterozoic rocks and hosts three tectonic units, namely the Western fold belt, the Kalkadoon Leichhardt belt, and the Eastern fold belt.

The Western fold belt is further categorised into the Lawn Hill Platform, Leichhardt River Fault Trough, Ewen Block, and the Myally Shelf zones, while the Eastern belt is categorised into the Mary Kathleen, Quamby-Malbon, and Cloncurry-Selwyn zones.

The Capricorn copper project occurs within the western part of the Leichhardt River Fault Trough and is connected with a regional scale transpressional dextral strike-slip system called the Mount Gordon Fault Zone (MGFZ).

Most of the copper mineralisation at Capricorn is hosted as a set of interconnected east to north-east trending faults and fault splays interconnected with the north-trending MGFZ. Mineralisation occurs in stockwork veins, breccias and as adjacent replacement of host rocks located within and close to the faults.

The mine features an existing portal at Mammoth deposit, which provides an access to the Mammoth Deeps, Greenstone, Mammoth North, East and Pluto deposits. The Esperanza South underground mine lies to the south-west of the existing Mammoth workings and comprises an independent decline and supporting mine infrastructure.

The current processing unit comprises a conventional copper sulphide flotation concentrator. The existing equipment is refurbished and a regrind mill has been added to allow the plant to process up to 1.7Mtpa of ore from multiple ore sources.

The concentrator comprises a single toggle jaw crusher, feeding a coarse ore stockpile, and a comminution circuit consisting of a closed semi-autogenous grinding (SAG) and ball mills paired with a hydro-cyclone cluster.

The rougher flotation circuit generates three separate rougher concentrates (high, middle, low grades), which passes through three cleaner flotation stages. The concentrate is then taken through the conventional thickeners for producing final copper concentrate.

The Capricorn copper mine is using the existing operating and support infrastructure, including a processing plant, existing mine declines and development, site infrastructure and offices, as well as established power and water supply facilities.

Byrnecut was awarded the mining contract for the underground Capricorn copper project in December 2016. The contractual scope also included underground mine rehabilitation, pre-production development, and production.

In 2017, Finland-based technology company Outotec was awarded an engineering, procurement and construction contract for a modular paste backfill plant, which comprised the Outotec Modular Paste Backfill Plant (MPB 80).

Engineering company Ausenco was engaged in managing the concentrator and surface infrastructure operations and maintenance (O&M) from 2018 to 2024. Ausenco improves plant output by 30%, plant runtime (or reliability) and copper recovery by 9%, copper concentration (product) rate by 7%, unit costs ($/t) by 10%.

copper ore grinding in a mobile vertical roller mill pilot plant - sciencedirect

Pilot scale vertical roller mill grinding tests were performed for chalcopyrite grinding successfully.Specific energy consumption and wear rates of existing conventional circuit and vertical roller mill were compared.Energy consumption of vertical roller mill is about 18% less than existing circuit.It is possible to decrease the operating costs about 38.1% by implementing vertical roller mill to the existing circuit.

Vertical roller mills (VRM) have been used extensively for comminuting both cement raw materials and minerals like limestone, clinker, phosphate, manganese, magnesite, feldspar and titanium. These mills combine crushing, grinding, classification and drying operations in one unit and have advantages over conventional machines and literature reports that 15% energy saving is achievable in cement grinding operations when compared to ball milling circuit. Such an improved performance in cement grinding operations encouraged the research studies on ore grinding applications. Within the scope of the study ore grinding performance of the vertical roller mill was investigated with mobile pilot plant. In this context, chalcopyrite ore of a plant having rod and ball milling circuit was ground under different operating modes e.g., air swept and overflow, and process conditions, then samples were collected around the system. The collected samples were characterized in terms of size distributions which were then used in comparing the performances of conventional and VRM systems. This study concluded that 18% saving in specific energy consumption was achievable together with the less wear on the internal components.
