All of these deposits are generally mined at the surface. The total recovery of the mineral deposit, the great control on the deposit, and the economy of sale are very significant in the choice of the mining method. This choice becomes even more important when the mineral deposit includes the extraction of lower grade minerals.

The country exports bauxite in its raw state, imports aluminum oxide, processes it in a smelter and then exports aluminum. This fragmented supply chain, which began in the 1970s, was beneficial to the companies involved, but not in the countries economic interests (Hart 1977). Since 1942, bauxite is mined in only one location (Awaso) in Ghana.
