The concentrated ores can be converted into metal oxide by using calcination or roasting based on the nature of the ore. The process of heating carbonate ore strongly in the absence of air is called calcination. Metals such as zinc (Zn), tin (Sn), lead (Pb), and iron (Fe) can be extracted by the process of calcination.
