Leaching of Calcareous Bornite Ore in Ammoniacal Solution

The leaching process of copper from calcareous bornite ore using ammonium persulfate as an oxidant in ammoniacal solution was investigated. The effects of stirring speed, temperature, initial concentration of ammonia and ammonium persulfate, and liquid-to-solid (L/S) ratio on the extraction percentage of copper from bornite ore were studied.

Selective impurity removal and Cu upgrading of copper

The gradual decrease of global copper resources is among the most urgent challenges for the mining industry. Sustainable utilization of copper sulphide flotation concentrate from iron oxide copper gold (IOCG) deposits is often constrained by the impurity elements (e.g. U, Th and F) and high levels of gangue minerals (e.g. iron oxide/hematite, U-bearing minerals and fluorite).

Chalcopyrite, Peacock Ore

Formation: Bornite and Chalcopyrite are both copper iron sulfide and major ores for native Copper.. They most typically grown in massive forms, with crystals being relatively rare. These minerals are usually formed in hydro-thermal veins in porphyry copper deposits, but can also be found in silica-pour igneous stones and contact metamorphic stones. Get price
