WebbRoasting. Calcination is a process in which ore is heated in the absence of air or air might be supplied in a limited quantity. Roasting involves the heating of ore lower than its melting point in the presence of air or oxygen. Calcination involves the thermal decomposition of carbonate ores. Roasting is carried out mostly for sulfide minerals.
