To be applicable to this process the ores must contain copper minerals in sulfide form; as mineral such as chalcocite (cu 2 s) chalcopyrite (cufes 2) and covellite (cus) in the concentrating operations these minerals are separated from the gangue material of the ore that might contain as little as 05% copper to form a concentrate .
The copper sulfide present in the sulfide ore (cufes 2) is converted by the process to partially dehydrated white copper sulfate which in the acid solution precipitates and thereby forms part of the light coloured precipitate.
Sep 01 2020&0183;&32;dissolution of sulfide ores requires oxidative leaching conditions then isr can be conducted by applying bacterial leaching a technology which is established in the copper industry for the treatment of copper sulfide ores in heaps and dumps (ghorbani et al 2016; petersen 2016)therefore the choice of the permeability stimulation approach which defines the leaching circuit the efficiency .
