raw materials used in bauxite


  • Uses of Bauxite Definition, Different Applications & Formula

    Bauxite is used in a lot of industries like the chemical industry, refractory, abrasive, cement, steel, and petrol industry amongst others In chemical, bauxite along with alumina is used in the manufacturing of aluminium chemicals In refractory, it is used as a raw material for making several products Bauxite is the main constituent materialThe Bayer Process also requires water; the global average input of fresh being 26 m 3 per tonne of alumina However, the process tends to discharge a high proportion (12 m 3) of this water in an unaltered form, meaning the average net “freshwater consumption” for the Bayer Process is 14 m 3 per tonne of alumina Seawater input and output is balanced (average 32 m 3 in and out)Aluminium for Future Generations – Raw Materials

  • Bauxite (raw) | EKCAG

    Aluminium ore bauxite can be found in a variety of applications As calcined bauxite, this raw material is a central raw material in the refractory industry thanks to its highly refractory properties This versatile mineral is also in demand in steel production as slag conditioner, in the production of refractory aluminium oxide cement, in road construction, in mineral wool production and asFeb 11, 2020· Produced from mined iron ore (its base raw material), steel is perhaps the most widely used component in auto manufacturing It accounts for roughly 80% of the weight of an average carWhat Raw Materials do Auto Manufacturers Use?
