beneficiation processes of bauxite
Beneficiation and mineral processing of bauxite and ...
Beneficiation and mineral processing of bauxite and feldspar. Bauxite is a sedimentary rock that is rich in alumina, the base for making aluminum. It is generally easy to mine because it is found near the surface of terrain. However, the process for separating the alumina from the other base elements in bauxite can be environmentally unfriendly.
