WebCopper is obtained from sulfide ores through a two-step process consisting of roasting the ore in the presence of oxygen and heating the resultant copper (I) oxide with powdered carbon. The overall reaction is as follows: 2Cu2S (s) + 302 (g) + 2C (s) → 2SO2 (g)+ 4Cu (s) + 2CO (g) Calculate the maximum yield of copper obtained from 1.60 kg of Cu2S. WebThe commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulphides. The percentage of copper in the actual ore is too low for direct extraction of …
