Hematite
Low-grade hematite ores, on the other hand, need to be upgraded to achieve the required iron content which involves more complicated ore beneficiation processes. The level of comminution required for the low-grade hematite ore is similar to high-grade ores to deliver products of the same size specifications, lump and fines.
