Mining is the process of extracting minerals from rocks buried under the earth's surface. Meanwhile, in open-case mining, minerals that lie at shallow depths are extracted by removing the surface layer. At the same time, Shaft mining is the method in which deep bores, called shafts, are made to reach mineral deposits that lie at great depths.

Bauxite Beneficiation: Efficient Way to Remove Silica in Bauxite
The main component of bauxite is Al 2 O 3, containing a small amount of Fe 2 O 3, SiO 2, and other impurities. The main objective of bauxite beneficiation is to lower the concentration of reactive silica, and also to increase the alumina content. In addition, bauxite beneficiation can also be used for iron extraction or iron removal.
