Chalcopyrite - an overview | ScienceDirect Topics
Chalcopyrite is essentially unleached under the mild oxidizing conditions of heap leaching (very slow leach kinetics). It can, however, be leached under oxidizing conditions at elevated temperatures or by microbial leaching under low-potential conditions (Gericke, Govender, & Pinches, 2010).This has led to extensive study into leaching of chalcopyrite concentrates asSEARCH FOR A NEW TECHNOLOGY PRODUCING COPPER FROM CHALCOPYRITE,The process is selective for chalcopyrite over pyrite. Copper recovery is 90 percent. Is suggested that this process could be operated for less than $0.28 per kg Cu, (at a copper price of $2,64 per kg Cu). 3.The Hydrometallurgy of Chalcopyrite in Ammoniacal Solutions,01-01-2019· Its chemistry allows for the selective dissolution of desired metals, leaving behind gangue including iron. Chalcopyrite is a copper sulphide ore known to be very stable and hence recalcitrant to many hydrometallurgical processing methods.
