Heap leaching - Wikipedia

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,THE ROLE OF METALLURGY IN ENHANCING BENEFICIATION,5 •South Africa possesses the world’s largest mineral resources by value. •It is also a significant global producer of many mined commodities. •The role of metallurgy in the mining value chain will be examined in terms of what is practised currently and the potential to expand. •The optimum degree of metallurgical beneficiation is highly dependent on economicPlatinum is produced in South Africa by Amplats, Impala,,The copper and nickel contents of UG2 ore are generally less than a tenth of those found in the Merensky Reef.,. 21 During concentration,,Crushing costs are
