Processing of Bauxite Ore. 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. From here, the ore is digested in a heated, pressurized vessel at temperatures
