Bauxite Crushing Plant Bauxite ore is a kind of mineral which is often collectively formed by gibbsite, a boehmite or a diasporeone. Bauxite can be widely used in many industries, among which the most important is to be used to refining aluminum, working as refractory and abrasive materials, and raw materials for high alumina cement.
Bauxite ore is formed when the surrounding soil or rock is dissolved by natural weathering processes until it forms a new type of rock that is usually rich in aluminum ore. Though both types are used for aluminum production, the most valuable type of bauxite ore is lateritic ore.
Processing of Bauxite Ores To Obtain Aluminum Bauxite, the primary aluminum ore, uses the Bayer Process to extract alumina from the ore. The processing begins with crushing to 1-2 inch particles and wet screening, to remove some silica fines, which are generally present with bauxite.
