Bauxite

The extraction of bauxite takes place by shallow, open-cut mining following the open-pit method. The bauxite ores content is of different types and the most amount of clay, and need to be washed before the process (Donoghue et al., 2014; Lee et al., 2017).

Aluminium Mining And Processing | Mining Informations

Bauxite is the only ore containing 20-25 percent of aluminium from where the metal is extracted and commercially produced. The open pit or surface mining process is carried in this case since bauxite is mostly found near surface areas where the layers of soil contain a mixed amount of various minerals, iron oxides and titanium dioxide.
