[0002] Bauxite, also known as bauxite or bauxite, is primarily composed of aluminum oxide. It is a hydrated aluminum oxide containing impurities. It is an earthy mineral that appears brownish-yellow or light red due to its iron content. It is opaque, brittle, and extremely difficult to melt. It is insoluble in water but soluble in sulfuric acid and sodium hydroxide solutions. It is primarily used in aluminum smelting and the manufacture of refractory materials. During the grinding process, bauxite contains a certain amount of iron minerals in addition to the main component, aluminum oxide, necessitating iron removal during processing.
