how to calcium carbonate produce calcium by heating

Calcium oxide - Wikipedia

Preparation Calcium oxide is usually made by the thermal decomposition of materials, such as limestone or seashells, that contain calcium carbonate (CaCO 3; mineral calcite) in a lime kiln. This is accomplished by heating the material to above 825 C (1,517 F), a process called ...
