The geometry and anatomy of the Los Pijiguaos bauxite

May 01, 20021. Introduction. Bauxite is the principal ore for the production of aluminium metal via a two-stage process that involves, firstly the refining of bauxite to alumina by a wet chemical caustic leach process (the Bayer process) and, secondly the electrolytic reduction of alumina to aluminium metal (the Hall–Heroult process).

Bauxite

Description / Application. A brownish - yellow clay-like / earthy mineral, it consists mainly of hydrated alumina, mixed with silica and iron hydroxide and is the most important source of aluminum. It is also known as aluminium ore and usually obtained from open cast mines.
