method of transportation is an iron ore slurry pipeline. 4.1.2 Iron Ore Beneficiation Iron ore occurs naturally in a variety of forms, from sand-like iron fines to solid rock masses. Crude ore, or ore mined in the natural state, seldom occurs in a pure state and requires some form of beneficiation.
The worlds resources are dominated by low-grade ore, though current world production of iron ore is largely by supply from deposits of high-grade ore composed of either rocks of massive hematite or pisolitic goethite. World iron ore production in 2013 was 2.95 billion tonne, with the major producers being China, Australia, and Brazil.

Vale has developed a revolutionary technique for processing iron ore in regions of high rainfall, which does not use water in the process. This technique avoids the need to build tailings dams, reducing impact on the environment. Called natural moisture or dry processing, it was put into practice, in 2008, on a trial basis at Caraj s, Par .
in the furnace where it reacts with the oxygen in the iron ore. Similarly, in the case of solid fuels such as coal, the carbon C acts as the reductant to form reduced iron and COx. This is different from blast furnace practice, where the ore is reduced mainly in the solid state, and carbon saturated iron in the liquid state is the product.
