24/04/2020Ghana Bauxite Company Limited — First discovered in 1914 in Ghana by Sir Albert Kitson, bauxite is an ore and the main source of aluminium. Though the British Aluminium Company gave approval for the mining of Bauxite in 1928 at Awaso in the country's western region, the exploration and mining works started only in the 1940s.

Most of the world's bauxite (aluminium ore) resources include valuable alumina minerals mixed with alumino-silicate clays. Insoluble components of the bauxite are removed by digesting the ore with very hot caustic soda (sodium hydroxide) in what is known as the Bayer process. Our treatment of red mud makes bauxite processing more cost effective.
