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.
