Bauxite is defined as a mineral ore composed primarily of aluminum oxides and/or hydroxides, along with smaller amounts of iron oxyhydroxides and clay minerals. It is specifically classified based on its aluminum content and weight ratios, meeting industrial standards for …

Bauxite is an aluminum ore that is widely recognized as one of the primary sources of aluminum. It consists of various minerals mixed together, including boehmite, gibbsite, and diaspore, along with other compounds. Bauxite is extracted and refined using processes such as the Bayer process to produce alumina, which is then used to manufacture aluminum. AI generated …
