Vale to invest 11 billion reais in dry iron ore processing over …
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%), 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.

How do you convert dry metric ton unit to metric tonne?
Dry metric ton unit is the metric ton unit without moisture. This measurement - dmtu is applied to Iron ore concentrate prices negotiations. If you agree to supply 100 t of Iron ore concentrate at 66%Fe with 10% moisture at a price of 120 dmtu, that means your revenue will be: 100 t * 0.9 * 0.66 * 120 = US$7,128.00. Ultimatelly, 100 metric ton at 10% moisture = …
