Refractory materials of calcined bauxite/bauxite powder factory
Product Description
Detailed Information Calcined Bauxite of Biyuan It is the main ore of alumina to make aluminum. Also used in the production of synthetic corundum and aluminous refractories. The bauxite is purified by the Bayer Process. First the ore is mixed with a hot concentrated solution of sodium hydroxide. The NaOH will dissolve the oxides of aluminum and silicon but not other impurities such as iron oxides, which remains insoluble. The insoluble materials are removed by filtration.
