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 ...

Acid Leaching - Copper Ore Treatment Method

The application of hydrometallurgical leaching to oxide and combined oxide and sulfide ores depends mainly on obtaining solvent at low cost and in holding initial plant costs within feasible limits. Dilute sulfuric acid-ferric sulfate has been found to be an excellent solvent for oxide minerals as well as for such sulfide forms as chalcocite and covelite but not chalcopyrite.
