Today, most of our iron ore production about 60% is through dry processing. The natural moisture processing is used at Carajás and Serra Leste mines, at S11D Eliezer Batista complex, in Pará, and at several plants in Minas Gerais. In five years, the company& 39;s goal is 70%, with R$11 billion of investments.
