Roasting of copper pyrites ores is for the following purposes:

Answer. Roasting: The process in which the concentrated ore is heated in blast of air and ore gets converted into oxide and impurities like sulphur, arsenic are also oxidised to their oxides and removed is called Roasting. It requires very high temperature and specialized furnace like Bessemer or reverberatory furnace. Rreaction: C u2. . S.F e2.
