Bauxite, also known as alumina or bauxite, is a soil like mineral primarily composed of alumina. It contains impurities in hydrated alumina, which appears white or grayish white, and sometimes appears brownish yellow or light red due to iron content. This mineral has a density of 3.45g/cm3, a hardness between 1 and 3, is opaque, and has a brittle and hard texture. It is worth noting that bauxite has extremely high stability and is almost difficult to melt. It is insoluble in water, but can be dissolved in sulfuric acid and sodium hydroxide solutions. In addition, bauxite can be further divided into raw materials and clinker, which are widely used and cover many important fields.
