Sulfuric Acid-Oxygen Leaching for In-Situ Extraction of Copper Chalcopyrite
Hydrometallurgical treatment of chalcopyrite by sulfuric acid based systems for primary recovery of copper is limited by the refractory nature of the mineral (Bartlett, 1973; Gerlach et al, 1973; Vizsolyi et al, 1967). At ambient temperatures and pressures, leaching of chalcopyrite is slow and current industrial processing is almost exclusively limited to conventional mining, milling, … Read more
