Bauxite mining. Bauxite is the ore used in the production of alumina, which in turn is the basic raw material in the aluminium manufacturing process. As the foremost step of the aluminium value chain, bauxite is a competitive determinant in the aluminium business.
Lime Component Limestone: Common forms of calcium carbonate used as raw material for cement manufacturing are limestone and chalk.Limestone is of predominantly fine grained crystalline structure, its hardness is between 1.8 to 3.0 of the Mohs scale of hardness and specific gravity 2. To 2.8. Limestone usually contains admixtures of clay substance or iron compounds, which influences its color.
Other materials could be used instead of bauxite for alumina production. Clay minerals, alunite, anorthosite, power plant ash, and oil shale could be used to produce alumina but at higher costs, using different processes. Silicon carbide and synthetic corundum are sometimes used in place of bauxite-based abrasives.
