03. Kumba Iron Ore
Africa's largest iron producer (and the fourth largest in the world) once again takes a spot in the top 20, though it slipped one position from second last year. Demand for iron from countries such as China has not hurt Kumba at all and it has seen its stock soar as a result. Today your R10,000 would have grown by 46.18% to a lovely R66,747. Kumba is part of the Anglo American groupof companies.
