It was used to manufacture aluminum until cheaper supplies were found in Canada.
Uses Of Bauxite In Ghana
Bauxite is used in the production of alumina, aluminum metal, boric acid, and other chemicals. Alumina is the principal ore from which aluminum is extracted. It consists mainly of a mixture of oxides of two elements: silicon and aluminum. Boric acid is a weakly acidic compound made from boron and oxygen.
