Chalcopyrite is the main mineral source of copper ore for extracting and producing copper. However, with the continuous mining of copper ore, the grade of chalcopyrite decreases year by year and its composition becomes more and more complex. The traditional pyrometallurgical extraction process has been unable to make …
Prior to melting, chalcopyrite is in a strong lattice formation, and is difficult to dissociate. As temperature increases, bond energy decreases, so the decomposition of chalcopyrite requires relatively lower potentials, but efforts for molten-state processing have been hindered by the persistence of high electronic conductivity of chalcopyrite.
Chalcopyrite is a copper-iron sulfide mineral that is usually brassy-yellow in color. ... Another beneficiation process is cyanidation, which uses a solution of sodium cyanide to dissolve gold particles in the ore body, which are then separated using filters or centrifuges. Commonly used to separate and recover gold from sulfide deposits.
The flotation concentration of metal-bearing ores is probably the most widely used mineral beneficiation process. Its efficiency depends on the minerals' preparation, i.e., grinding, flotation reagent types and concentrations, and other parameters of the flotation process, such as pulp pH values, oxidation–reduction conditions, temperature ...
