Optimum Calcination Conditions for Preparation of Magnesium Oxide and Magnesium Carbonate from Magnesite
Magnesite is a magnesium carbonate, its chemical formula is magnesium carbonate (MgCO3), theoretical composition: MgO47.81%, CO252.19%, density 2.9-3.1g/cm3, hardness 3-5. Magnesite can be divided into two types: crystalline and amorphous according to its crystallization state. Crystalline magnesite is rhombohexahedral, columnar, plate-like, granular, dense, soil-like and fibrous, etc. It often contains calcium and manganese isomorphs. Fe2+ […]
