Extraction Process of Aluminium from Bauxite Ore

It is essential that the Al2O3 (alumina) be obtained substantially free from these impurities as otherwise the iron oxide and silica would be reduced and contaminate the metallic aluminum produced in the Hall (or Heroult) Process The separation of the alumina from the impurities in the bauxite ore is usually accomplished by the Bayer Process

Cement

Cement is a mixture of calcium silicates and smaller amounts of Tetra-calcium alumino-ferrite calcium aluminates that react with water and cause the cement to set The requirement for calcium is met by using high calcium limestone (or its equivalent calcareous raw material) and clay as the source of most of the silica alumina Iron Finished cement is produced by finely grinding together
