Read More- Copper pyrites is the ore of copper in which copper is present in the form of its sulphide. So, this gives a roasting reaction to give copper oxide as a main product. But alongside this, the ore also contains iron. So, we add some amount of silica in order to remove iron as slag. The reaction can be given as under.
