Advances in high-temperature heap leaching of refractory ...

The heap leaching of copper ores is an example of such a trend, where heap leaching was initially applied only to the acid leaching of oxide ores. The most important factors to be considered in oxide heap leaching are the copper dissolution, acid consumption, and gangue chemistry. The rate at which acid can be supplied to the heap is constrained by the increase in undesirable gangue reactions ...

The twenty percent of the world’s copper production is accomplished by heap leaching of ores from mines and processing plants as well as waste ores from dumps and further processing by solvent extraction and electrowinning (SX/EW) [16]. Biological leaching was proved to be efficient for sulfides of Co, Ga, Mo, Ni, Zn, and Pb [16].

Heap Leaching - an overview ScienceDirect Topics

Heap leaching was initially applied to acid leaching of copper oxide ores and later extended to secondary sulfides and mixed oxide-sulfide copper ores. By introducing bacterial activity and forced aeration to the heaps, an oxidative environment suitable for sulfide oxidation can be achieved. Application of bioheap leaching to chalcopyrite ores is complex and generally encounters poor leaching ...
