The Refining of Bauxite into Alumina. The first step in the commercial production of aluminum is the separation of aluminum oxide from the iron oxide in bauxite. This is accomplished in a refinery or alumina plant using a technique developed by Karl Joseph Bayer, an Austrian chemist, in 1888. In the Bayer Process, bauxite is mixed with caustic

Aluminium

Extraction process Bayer process The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide). Bauxite, the most important ore of aluminium, contains only 30-50% aluminium oxide (Al 2 O 3), the rest being a mixture of silica, various iron oxides and titanium dioxide. The aluminium oxide must be purified before it can be refined to aluminium metal.
