Vale has more than just one iron in the fire. Iron ore and pellets account for more than two-thirds of Vale's sales, and the company accounts for a third of the world's ocean-shipped iron ore. Vale also mines for bauxite, nickel, kaolin, and potash. Other products include steel, copper, and aluminum. It has holdings in hydroelectric power generation and in the rail and shipping businesses, mainly to support its mining activities in Brazil. The company is the world's second-largest iron ore miner, having grown dramatically with the 2006 acquisition of Vale Limited (formerly Vale Inco). To raise cash, in late 2016 Vale agreed to sell its fertilizer business to Mosaic for $2.5 billion.
