Copper Leaching Method - Metallurgist Mineral

Mar 25, 2017  In leaching roasted mill tailings the consumption of acid appears to be small—about 50 lb. acid per ton of tailings handled—even with very fine material. This illustrates the benefit derived from roasting substances containing colloids, such as mill slimes, when the copper is to be subsequently extracted by lixiviation.

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

Oct 01, 2011  For the copper sulfide ore, copper recovery was independent of the crushing method since about 80–90% of copper is recovered during the initial period of leaching . Recovery values were higher than those for the copper oxide ore samples, apparently due to the higher head grade, greater grain exposure and perhaps a more aggressive leach solution.
