This is because it is easier to obtain metals from their oxides (by reduction) than from carbonate or sulphide ores. So, before reduction the ore must be converted into metal oxide which can then be reduced. Calcination or roasting is done depending on the nature of ore, to convert the ore into oxide. A carbonate ore is converted into oxide by calcination whereas a sulphide ore is converted into oxide by roasting.
