Vale said: "Dry processing is linked to the quality of the iron ore extracted from mining. In Carajás, as the iron content is already high (above 64% Fe), the ore is only crushed and sieved, so it can be classified by size (granulometry). "In Minas Gerais, the average content is 40% iron, contained in rocks known as itabirites.
