Vale has 19 iron ore mines and 10 industrial beneficiation plants in the QF region. These produce almost 200 million tons per year of iron ore, which represents approximately 70% of the total production in the region (DNPM, 2012; Vale S.A., 2012). Production is forecast to increase approximately 10% between 2013 and 2017, and 50% by 2030.
