Uses. Bauxite is a raw material used primarily in the production of aluminium.The bauxite ore is refined into alumina before being smelted into aluminium. Australia is known for its high-grade ore, especially in the Weipa and Gove deposits. The quality of bauxite ore is determined by its available alumina (Al 2 O 3) content.The presence of impurities, which make the ore more
