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 ...

Pre-feasibility studies of copper hydrometallurgical plants : Pre-feasibility study is conducted first to sort out applicable scenarios. It is desirable to do some pre-feasibility studies of your own or with help of consultant before evaluation feasibility study done by engineering offices. If you find out early that the proposed plant design project idea is not feasible, it will save your money.

8/31/2013· Bioleaching of chalcopyrite often encountered the formation of passivation layer, which inhibited the leaching process and resulted in a low leaching rate. This inhibitory effect can be eliminated by thermophilic bioleaching. The industrial test of BioCOP technology based on thermophiles was successfully completed, which confirmed the feasibility of chalcopyrite bioleaching.

Heap leaching relies on a leaching agent moving through a bed of heaped ore to extract the metallic components: Crushed ore is stacked on a leaching pad and irrigated with the leaching agent. The leaching agent chemically reacts with the metal in the ore to dissolve the copper into the solution as it percolates through the heap.
