#1:. Aliko Dangote, $15.7 billion Nigerian, Sugar, Cement, Flour
Still the richest black person in the world, Dangote has lost close to $10 billion since March 2014. Devaluation of the naira and falling stock prices hurt his four publicly-listed companies, but not his ranking on this list.
Dangote, 57, made his first fortune selling cement, sugar and flour, and his second manufacturing them. Dangote Cement is Africa’s largest cement manufacturer, and is worth $15 billion.
Dangote is building an oil refinery, due for completion in 2016 with a 400,000-barrels-a-day capacity. He hopes to reduce Nigeria’s dependence on oil imports.
