Africa - Africa - Metallic deposits: In North Africa reserves of iron ore are concentrated in the Atlas Mountains and in the western Sahara. Egypt, however, has medium-grade reserves, of which the most important are at Al-Baḥriyyah Oasis. The ore deposits in Morocco and Tunisia, which were once of considerable importance, have been severely depleted.
Ghana is considered as one of the major exporters of manganese in the world. The exploration of manganese in Ghana can be traced back to the early 1970s. Since then, the exploitation of this mineral has continued all over the country. The manganese from Ghana is exported to various foreign and especially European countries where it is put into use.

Abstract. This relatively simple deposit illustrates the way manganese oxide Minerals can accumulate in a laterite profile. The manganese originated as a metamorphosed manganiferous sediment; quite unworkable in itself, but which has been concentrated on an old erosion surface, and which also carries ferruginous and aluminous laterites.
