Iron Ore Developments Surge in West Africa

In 1951 the first ton of iron was shipped from West Africa; ten years later the total export exceeded 4 million tons, and an optimistic forecast for 1970 indicates a production capacity of something around 40 to 50 million tons. The quality of the ore varies from normal hematitic concentrates, through naturally enriched hematitic direct shipping ores with comparatively high content of ore fines, to dense, hard, rich lump ores of magmatic character. West Africa is largely composed of folded Pre-cambrian rocks trending generally northeast to southwest. They are exposed over about one third of West Africa and are part of the vast continental plateau which has an average elevation of about 1300 ft in this area.
