1.Introduction of bauxite
Bauxite, also known as bauxite or bauxite, is mainly composed of alumina, a hydrated alumina containing impurities, and is a soil-like mineral. White or grayish white, brownish yellow or light red due to iron content. The density is 3.45 g / cm3, hardness is 1 ~ 3, opaque, brittle, extremely difficult to melt. It is insoluble in water and soluble in sulfuric acid and sodium hydroxide solution. It is mainly used for smelting aluminum and making refractory materials.
2.Main use of bauxite
Metal applications : The main function of bauxite in metals is to produce aluminum. After all, metal aluminum rarely exists as natural aluminum in nature. Whether oxide or hydroxide, aluminum is the second most important metal in the world after steel.

Non-metallic applications :
1. Refractory materials : The raw materials of bauxite are common refractory and anticorrosive materials in industry. That heat resistance is about 1700 degrees. In some electric furnaces and blast furnaces, its fire resistance is much better than ordinary clay.
2, do casting coating : bauxite is mostly used for casting coating, mainly clinker after processing into fine powder, such as wear mold casting coating, can be used for military, aerospace, instrumentation, etc.
