Vale to invest 11 billion reais in dry iron ore processing

May 15, 2019· Dry processing is linked to the quality of the iron ore extracted from mining. In Carajas, 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.
