Iron ore as a main dry cargo - OpenSea

Iron Ore: The King of the Dry Bulk Shipping. The iron ore is the dry bulk cargo with the largest trading volume per year, above coal and grains. Iron ore is found in nature in form of rocks, usually mixed with other elements and after it is processed by various industrial processes, it is sold to steel companies.

Vale to invest 11 billion reais in dry iron ore processing ...

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.
