Leaching Equipment

Percolation Heap leaching (see Mular et al pp 1571–1630 loc cit ) is very widely applied to the ores of copper and precious metals but percolation is also conducted on a smaller scale in batch tanks or vats and in continuous or dump extractors In the heap leaching of low-grade oxidized gold ores for instance a dilute alkaline solution of sodium cyanide is distributed over a heap of

Process

Most mining companies favor the economic feasibility of heap leaching considering that heap leaching is a better alternative to conventional processing methods such as such as flotation agitation and vat leaching Additionally dump leaching is an essential part of most copper mining operations and determines the quality grade of the produced material along with other factors

Copper Dump Leaching and Management Practices That

The leach solution flows by gravity through the dump and then over the slope of the native ground beneath the dump to a collection point usually a pond at the downgrade toe of the dump Historically dump leaching evolved from secondary efforts to recover copper from waste rock and mine overburden generated by conventional mining methods (principally open-pit operations)

Heap leaching

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 re-separate 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
