At stone quarry, mining crushers like heavy duty jaw crusher, cone crusher, impact crusher, VSI crusher are widely used. In addition, we can manufacture proved small jaw crusher, HP cone crusher, single cylinder cone crusher, sand making machine for the customers application.

The mining crusher is suitable for producing building materials, roadbaselike construction aggregate building aggregate, riprap, sand, and gravelfrom natural stones such asbasalt, granite, limestone, marble, cobble stone, river stone, concrete, gravel, manufactured sandetc. at open-pit mine, and the mining crusher in stock features with high crushing capacity, low costs, low downtime, easily operate, versatile application etc.

Ore dressing plant is widely used for ore processing & extraction at an ore beneficiation plant to concentrate ore minerals. The ore dressing process contains mine crushing, screening, grinding, washing, drying and so on.

The popular grinding mills are ball mill, MTM trapezium mill, MTW trapezium mill, coarse powder mill, ultrafine mill, Raymond mill etc. The final grain size of the product can be down to 2500 mesh (or 0.005mm).

While mining nodes can be found just about anywhere they're most often found in rocky areas, on the side of cliffs, in construction and quarry areas, and caves. When it comes to caves, the deeper and larger the cave, the more likely for there to be mining nodes; Very deep and complex caves are also more likely to contain rare mining nodes.

Mining nodes come in a few different forms. Iron Veins are the most basic vein, and provide Iron Ore, Raw Stone, and a chance for Pure Iron Ore. Fortuna Veins give a chance for Copper Ore, Silver Ore, Gold Ore, Archeum Ore, Crystals, or Precious gems. Fortuna Veins have a chance to appear immediately following mining of an Iron Vein.

In the western region of Nigeria, there is distributed with lots of alluvial gold mine and native gold. The following states have abundant gold ore resources: Osun, Edo, Niger, Kebbi, Kaduna and Sokoto. In this country's northwest and southwest areas, it have found large scale commercial extraction native gold ore site. According to information, these native gold ores are buried shallow and the level is relatively high. The production costs of the gold ore are per ounce 50 dollars.

Nigeria is rich with gold ore and how to make best use of these native gold ore resources becomes very important for the local economic increasing. For all of us, we know that, native gold ore does not satisfy the detailed production requirements and it needs to be processed into the high grade gold ore.

Native gold ore materials will be extracted, crushed, grinded, washed and benefited. Then these processed materials will be sold or used in the market. Nigeria whole gold ore processing line includes the gold ore mining stage and gold ore washing plant.

SBM's range of services for gold ore processing covers all processes needed for the recovery of gold, from ore to bullion and fine gold, converting run-of-mine (ROM) ore into saleable products, integrating engineering and process know-how in development and optimization of plant designs, and delivering processing facilities to global environmental standards.

Native gold ore mining processing plant in Nigeria refers to the gold ore extraction stage, gold ore crushing and grinding stages. In gold ore extraction stage, the native gold ore will be got from the mineral monitions. These gold ore will be taken to the mining processing plant. In the mining processing plant, gold ore crushing and grinding stages will play great role.

Gold ore crushing mining processing plant will break the large scale gold ore materials into small size with crushing machine. SBM is a professional crushing machine manufacturer and it has produced lots of high efficient crushing machine for the mineral ore mining production line and construction industry. SBM has the PE series jaw crusher, PEW series jaw crusher, PF series impact crusher, PFW series impact crusher, cone crusher, hammer crusher, VSI crusher and so on. These different kinds of crushers can be used in the mineral ore production line.

When the gold ore is crushed into small size, some customers will need the grinding machine to process the gold ore materials into further smaller size to powder. Grinding machine from SBM will help to grind the crushed gold ore materials into powder. These high quality and low costs gold ore grinding machine is vital for gold ore mining processing plant.

If the gold ore is processed in mining production line, next will be the gold ore washing stage. Gold ore washing machine generally can make the unpurified gold ore into high grade gold ore materials without mud or other materials.

SBM gold ore washing processing machine has new seal structure and reliable driving equipment which can make sure the cleaning effect and a kind of high efficient. This gold ore washing machine is welcomed by Nigeria for the following great features:

According to the above text, SBM designs the specific gold ore processing production line for Nigeria local customers. The local gold ore hardness is 2.5-3.0. The detailed gold ore processing production line involves the gold ore PE series jaw crusher + gold ore cone crusher + gold ore PF series impact crusher + gold ore XSD sand washer + the auxiliary equipment. Besides the main crushing and grinding processing machine, it also needs the auxiliary equipment, such as the vibrating feeder, vibrating screen, belt conveyor. The whole gold production line will help local clients get high grade gold ore with low operation costs.

Prominer maintains a team of senior gold processing engineers with expertise and global experience. 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.

Prominer has been devoted to mineral processing industry for decades and specializes in mineral upgrading and deep processing. With expertise in the fields of mineral project development, mining, test study, engineering, technological processing.
