Nigerian commodities titan Aliko Dangote is also Africa’s cement king. In late 2010, he listed Dangote Cement on the Nigerian Stock Exchange. The company integrated Dangote’s cement investments across Africa, including Benue Cement, formerly listed on the Nigerian Stock Exchange. It’s now the largest company on the Nigerian exchange, with a market capitalization of $10 billion. In August, Dangote received approval from the Central Bank of Nigeria to invest $4 billion to build a new cement facility in the Ivory Coast. He’s also building a $115 million cement plant in Cameroon, and owns plants in Zambia, Senegal, Tanzania and South Africa, among others.
