Fine-grained iron ore is a type of iron ore that has a smaller particle size compared to other types of iron ore. Beneficiating fine-grained iron ore is a challenge due to its high impurity content and low iron grade. However, with the advancement of technology, it is possible to beneficiate fine-grained iron ore to improve its quality and increase its economic value.
In general, iron ore beneficiation is done at the mining site. The concentrated iron ore is subsequently sintered or pelletized, depending on the grain size distribution, before it is charged to an ironmaking plant.
