Using of the Principle of Autogenous Crushing in the Production of Caustic Magnesia

Magnesium MgO exists in nature in large quantities as magnesite (MgCO 3 ) and dolomite (CaMg (CO 3 ) 2 ), and in lesser amounts than oxide in the form of mineral called periclase. Magnesite refractory material containing MgO may be obtained from the high purity magnesite ore simple purification and subsequent calcination at a temperature of 500-700 °C.
