Bauxite is a material that occurs naturally and is heterogeneous in nature. It is composed primarily of one or more aluminium hydroxide 网页Bauxite deposits are traditionally regarded as economic sources of aluminum (Al). However, bauxite deposits are also important sources of Ga as a byproduct commodity because the close geochemical affinity of Ga to Al enables Ga to substitute easily in rock-forming aluminosilicates such as feldspar (Burton and others, 1959). 网页15 小时前Bauxite: India’s total reserves of bauxite (the ore from which the aluminium metal is produced) were estimated at about 3,290 million tonnes, as of April 1, 2005.
