Bauxite, also known as bauxite or bauxite, is mainly composed of alumina, which is hydrated alumina containing impurities and is an earthy mineral. White or off-white, brownish-yellow or light red due to iron content. Density 3.45g/cm3, hardness 1-3, opaque and brittle. Extremely difficult to melt. Insoluble in water, soluble in sulfuric acid and sodium hydroxide solution. It is mainly used for aluminum smelting and refractory materials.


Aggregate, raw material, clinker, fine powder (the specifications are 100 mesh, 200 mesh, 250 mesh, 300 mesh, etc., and can also be customized according to customer needs)

  1. Aluminum smelting industry.
  2. Precision casting. Bauxite clinker is processed into fine powder and then cast.
  3. For refractory products. High bauxite clinker refractoriness up to 1780℃, strong chemical stability, good physical properties.
  4. Aluminum silicate refractory fiber. It has the advantages of light weight, high temperature resistance, good thermal stability, low thermal conductivity, small heat capacity and mechanical vibration resistance.
  5. Using magnesia and bauxite clinker as raw materials and adding appropriate binder, it can be used for casting steel barrel lining.
  6. Manufacturing bauxite cement, grinding materials, ceramic industry and chemical industry can be made of aluminum compounds.
