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. In cases where after the initial processing steps the iron ore fractions are of inferior quality (too fine or low iron content ...
