Why are sulphide ores converted to oxide form before reduction to metal

Answer Because it is easy to obtain the metal The process of conversion of sulphide ore into oxide is called Roasting We can reduce the sulphide by using carbon aluminium etc We not only reduce sulphide ore into oxide but also carbonate ore into oxude and the process is known as calcination
