An alternative technique for the beneficiation of these ores is the calcination. Calcination is the process of heating the ore to a high temperature ranging from 800 to 1000°C to decompose CaCO 3 and MgCO 3 to CaO, MgO and gaseous CO 2. The CaO and MgO formed are then removed as hydroxides by quenching the calcined product in water and washing.
