Why is chalcocite roasted and not calcined in the recovery ,, Nov 01, 2018· Roasting involves heating of an ore in the presence of excess of air while calcination involves heating of the ore in the presence of limited supply of air Roasting of chalcocite is necessary because it not only removes the impurities of S, P, As, Sb, etc, present in it as their volatile oxides but also partially oxidises Cu 2 S to Cu 2 ODevelopment of partial extraction methods to estimate ,, Development of partial extraction methods to estimate abundance of copper-iron sulphide minerals in the Escondida Norte porphyry copper deposit, Chile , analysis and combined with a novel approach to interpret the analytical results as normative mineral estimates of chalcocite, covellite, chalcopyrite and pyrite content ,A kinetic study of the leaching of chalcocite in an ,, A KINETIC STUDY OF THE LEACHING OF CHALCOCITE IN AN AMMONIA-OXYGEN SYSTEM by Steven Douglas Light , 53 Comparison of Predicted and Experimental Extraction for Run Run 11 77 , current smelting methods In January, 1975, a hydrometallurgy plant ,Innovations: How Hydrometallurgy and the SX/EW Process ,, To be applicable to this process, the ores must contain copper minerals in sulfide form; as mineral such as Chalcocite (Cu 2 S), Chalcopyrite (CuFeS 2) and Covellite (CuS) In the concentrating operations these minerals are separated from the gangue material of the ore, that might contain as little as 05% copper to form a concentrate ,Chalcocite: The mineral Chalcocite information and pictures, Chalcocite is an important copper ore It has a high copper content and the process of extracting the copper from the sulfur in Chalcocite is relatively easily Chalcocite is also an important collector's mineral, and good crystals command very high pric.
