Why the Extraction of Copper from Chalcopyrite is so ...
So, extraction of Copper from it becomes very difficult it is a lengthy process because. (i) It contains many impurities in such a high amount that the percentage of Copper in it becomes only 23%. (ii) Copper has more affinity to sulphur than Fe. So, the Cu 2 O formed through roasting of the ore is later converted into Cu 2 S by reacting ...

In the extraction of copper, the copper matte is a mixture of:
copper (II) sulphide and iron (II) sulphide. The chemical formula of copper matte is Cu 2. . S+FeS. It is a combination of copper sulphide and iron sulphide. It is a phase in which extracted metal is converted into crude metal which is a final product. 80−70% of copper matte is used 80−95%. 5−17% metallic copper, Fe−Co alloy etc are used.
