Bauxite processing and aluminium production in Africa
Aluminium consumption is extremely low in Africa, outside South Africa, and is mainly concentrated in North Africa, Egypt and Nigeria. Consumption levels are, however, far from those of developed countries (22 kilograms per head in the USA, 15 in Japan, 7 in France and in the USSR).
Aluminium production in Africa is about three times higher than consumption, but while the former is, for the most part, exported, the latter is covered mainly by imports. Africa's relative shares in world output are 14% for bauxite, 0.02% for alumina and 2.6% for aluminium. Although exceeding the domestic needs, aluminium output is well below the level which could be reached by processing all local bauxite, and this applies to an ever greater extent to alumina. Also, the fact that aluminium production is higher than the production of alumina implies that the former depends on imported alumina. While the aluminium refineries of Ghana, Egypt, and Cameroun import alumina, the bauxite producers export their production in a raw form.
There are, however, important investment projects for aluminium, in Guinea, of course, but also in Cameroun, Nigeria, Sierra Leone, Zaire and Madagascar. The most advanced are on the bauxite fields of Tougue, Dabola and Ayekoye in Guinea. The size of each of these projects is equivalent to present African consumption, therefore even their partial implementation will increase the aluminium surplus of the continent and substitute the export of aluminium (and/or alumina) for that of bauxite.

Production of alumina and aluminium is heavily concentrated in developed countries which are the main consumers. They import alumina to produce aluminium and they import even greater quantities of bauxite to produce alumina. Australia, Surinam and Jamaica, unlike Guinea, however, process a good part of their bauxite output.
