Pressure leaching of copper sulphides in perchloric acid solutions
The leaching of covellite (CuS), chalcocite (Cu₂S), chalcopyrite (CuFeS₂) and bornite (Cu₅FeS₄) was carried out in a shaking autoclave in perchloric acid solutions and using moderate pressures of oxygen. The temperature range of investigation was 105-140°C. It was found that covellite, chalcocite a...
