    Dry processing is associated with the quality of the iron ore from the mine face. In Carajás, as the iron content is already high (above 65% Fe), the material is only crushed and screened to be classified by size (granulometry). In some mines of Minas Gerais, the average content is 40% Fe in itabirite.
