May 13, 2019 Dry processing is linked to the quality of the iron ore extracted from mining. In Caraj s, as the iron content is already high above 64, 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.
