Buxite Industry In Ghana. Ghana is a country located on the west coast of Africa, the Gold Coast. Known for having the best oil reserves in the world, Ghana's other exports such as timber, diamond, manganese, cocoa, gold, and bauxite are what feed the country's economy. The main source of aluminum comes from the aluminum ore, Bauxite.

A process for removing silica from bauxite is disclosed. The method includes the step of mixing bauxite with a caustic liquor to form a mixture and to dissolve and stabilise at least a substantial part of the reactive silica from the bauxite. The caustic liquor is selected to have a high caustic concentration and a high alumina content.

The extraction of aluminium involves two steps that is, purification of bauxite by Baeyer's process and electrolysis of alumina. 1. Purification of bauxite by Baeyer's process In the Baeyer's process, the bauxite ore is heated with concentrated NaOH solution under pressure (Aluminum is purified by leaching method).The alumina dissolves as sodium meta aluminate.

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.
