treatment of bauxite industry

treatment of bauxite industry. Typical deposits range in thickness from 3 to 15 m. The majority of the bauxite can be mined and processed without beneficiation (further treatment of the ore to concentrate the minerals), but the ore in the north of Brazil and in Vietnam has a high clay content and has to be washed before processing.

Treatment Of Bauxite Industry

Treatment Of Bauxite Industry. Bauxite is one of the worlds most abundant minerals and is strip-mined in many places. Nearly all is processed into alumina for aluminium production. Bauxite contains iron-bearing clay or red mud, which often leaves stains on the hold paint that can prove difficult to remove. Bauxite is an aluminium ore and is the main source of aluminium.
