Iron ore :: ArcelorMittal Liberia

ArcelorMittal Liberia's iron ore is a direct shipped iron ore (DSO) product. DSO means that apart from some primary crushing, screening and blending at the mine, the iron ore is mined, shipped and consumed in about the same form as it is extracted from the ground. DSO is a sintering fines material. It is sold to steel

Iron Ore and it's future - Magnetite

The magnetic properties of Magnetite make it easier to concentrate than haematite. Magnetite's exothermic conversion to Fe 2 O 3 is a significant energy input (saving) in sintering and in pellet making. However, the key thing for both magnetite and haematite concentrates is to have high iron grades and low deleterious impurities in the …
