Low-grade hematite ores 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 the same products lumps and fines.

Beneficiation Plants And Pelletizing Plants For Utilizing

In the case of low-grade mines or where the product iron grade needs further improvement the secondary crushing is replaced by a beneficiation process. As shown in Fig. 1 the beneficiation process mainly comprises the sub-processes of grinding separating and dewatering. 2.2.1 Grinding Grinding is a sub-process of finely grinding ore

Advances In Low Grade Iron Ore Beneficiation

iron ore is expected to rise by more than 200 million tonne per year to meet the internal demand amp export. This additional requirement of iron ore will need beneficiation of low grade orefines to get the major portion of increased demand. This paper deals in brief to use of available methodologies for beneficiation of iron ore in Indian context.
