  • Bayer Process: Manufacturing Of Alumina Making Alumina

    Alumina is symbolised as Al2O3. Alumina has the appearance of white solid like table salt. Alumina has a boiling point of 2980 degree Celsius and melting point of 2040 degree Celsius. Its molar mass is 101.96 g/mol. The Bayer Process: Alumina is the main components of bauxite, so bauxite is refined in order to produce
