Factors controlling copper solubility and chalcopyrite

The Sungun porphyry copper deposit is hosted in a Diorite/granodioritic to quartz-monzonitic stock that intruded Eocene volcanosedimentary and Cretaceous carbonate rocks. Copper mineralization is associated mainly with potassic alteration and to a lesser extent with sericitic alteration. Based on previously published fluid inclusion and isotopic data by Hezarkhani and Williams-Jones most of

Chalcopyritean 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 as an alternative to smelting.
