Bauxite processing, however, is less developed in Africa, and there is only one alumina smelter, located in Guinea, which transforms only a small fraction of the locally produced bauxite ore. Lastly, the steel industry is totally absent in the main iron ore producing countries.
1. . ScopeThis document will critically review existing and potential processes for the processing of high silica bauxites. High silica bauxites are usually considered to be those with reactive silica contents in excess of ∼. 8% by weight of the bauxite (reactive silica is defined later in this paper).. This review is limited to bauxites as feedstocks for the processes.
