chemical process of bauxite mining

The Chemistry and Processing of Jamaican Bauxite. The Chemistry of Bauxite and Alumina The first commercial extraction of alumina Al 2 O 3 from bauxite has been attributed to Henri Sainte-Claire Deville in about 1854 Soon after this in 1888 Karl Joseph Bayer described what is now known as the Bayer Process which led to a dramatic reduction in the cost of aluminum metal

Ore genesis - Wikipedia

Endogenous Magmatic processes. Fractional crystallization: separates ore and non-ore minerals according to their crystallization temperature.As early crystallizing minerals form from magma, they incorporate certain elements, some of which are metals.These crystals may settle onto the bottom of the intrusion, concentrating ore minerals there. Chromite and magnetite are ore minerals that form in

Electrolytic Extraction of Aluminium from Bauxite and Alumina

The main source of aluminum is the extracted from bauxite by electrolysis. The extraction proceeds in two stages. In the first stage, the crude bauxite is purified to yield pure anhydrous aluminum oxide, which is then electrolyzed in the second stage.

Bauxite Types and Uses - Australian Bauxite Limited

Bauxite is aluminium-rich ore that is used for aluminium production (the metallurgical bauxites) and for production of refractory materials, chemicals or cements (the non-metallurgical bauxites). Metallurgical bauxites are sub-divided into two basic types based on the processing methods that must be applied to them at the alumina refinery stage
