copper leaching operates

Copper Smelting - an overview ScienceDirect Topics

The main differences of bioleaching from the chemical leaching involve that the leaching operates at room temperature, and the process proceeds with more slow speed. From the results of the studies [ 37–39 ], it is known that the factors influencing the recovery of nonferrous metals recovery from copper smelting slags in chemical (sulfuric ...

Pyrometallurgy - an overview ScienceDirect Topics

Sometimes, leaching can be performed by microbes, a process that is an attractive and profitable process for the dissolution of metals from laterite ore. Microbe-based leaching is often the preference when typical mining approaches are ineffective or too expensive. Such treatments have offered access to copper, gold, lead, nickel, and zinc.
