· Heap leaching is used to extract gold, copper, silver, uranium, and iodine. This method was first employed to extract copper at the Bluebird mine in the US in the early 1960s, and then by several gold mines in the western parts of the US a few years later. Since then, heap leaching has been adopted successfully by many mines across the world.
Gold CIL (Carbon in Leach) Process is an efficient design of extracting and recovering gold from its ore. By cyaniding and carbon leaching crushed gold ore slurry simultaneously, CIL process lower the gold mining operation cost and increase gold recovery rate to a degree of 99%.
Pump leaching is a process that grind gold mine with low grade to a certain particles, heap up on the leakageproof bottom mat that concreted by pitch, concrete or plastic cloth, spray the low concentration cyanide solution, alkaline solution, nontoxic solvent, dilute sulphuric acid on the stock heap, make the gold dissolve, the solution with gold heap up, then use active carbon to absorb or use zinc .
· Heap leaching has become a popular method of extracting gold, writes mining consultant Nicolaas C. Steenkamp and Leon Louw, writer, editor and specialist in African affairs and mining. Heap leaching is used to extract gold, copper, silver, uranium, and iodine. This method was first employed to extract copper at the Bluebird mine in the US in ...
· Heap leaching is not that popular in South Africa because it is more applicable to shallow opencast mining, and South African gold mines are mostly underground operations. The method is, however, being used on a large scale in the copper mines of South America and, according to Bundo, it will be used more and more on the African continent in future.

Heap leaching (HL) is a flexible and economic mineral processing method, commonly used to extract gold from lowgrade gold ores. In this process, ore is firstly crushed to fine particles. By spraying leaching solution to the large piles, the goldcontaining solution is leached.
Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and reseparate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the ...

Gold mine heap leaching process crushed by jaw crushers and cone crushers to a certain particle size 3050mm, raw ore is directly sent for heaping or granulated to make finer particles agglomerate into coarse powder, and then transported to the ore heap...
The leaching agitation tank is mechanical agitation machine used in cyanide leaching operation of gold mine. The working principle of leaching agitation tank is: with dual impellers rotating and agitating, ore pulps move downward and then diffuse along damping plate. Air is fed in tank from the lower end of shaft, and blended with ore pulps to form uniform suspending mixed liquid.
Because the flotation method can only maximize the concentration of gold into various sulfide mineral concentrates, and can not finally obtain the finished gold, therefore, there are only a few gold selection plants using a single flotation process, generally the flotation is used as a joint. A process of the process is adopted. At present, China''s gold selection plants using a single ...
