Utilization of charcoal in the iron-ore sintering process

The results of the studies suggest that the size of plant and sawdust biomass particles should be smaller than those in case of coke where the threshold is less than 3 mm. Charcoal should be used in fraction under 3 mm; for sawdust the particles should be under 1 mm and for plants from 0.6 to 0.8 mm. Biomass is characterized by relatively high and

Iron Ore

Iron ore minerals, particularly hematite and goethite, are beneficiated by a combination of size fraction, preconcentration, and flotation in stages (Fig. 13.45) on ore requires removal of silicate impurities of a finer size by flotation for higher-grade products of +60% Fe. ROM ore at 400–600 mm is fed to a primary crusher with product set at –40 mm.

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 & export. This additional requirement of iron ore will need beneficiation of low grade ore/fines 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.

iron processing

Crushed ore is divided into various fractions by passing it over sieves through which undersized material falls. In this way, lump or rubble ore (7 to 25 millimetres in size) is separated from the fines (less than 7 millimetres). If the lump ore is of the appropriate quality, it can be charged to the blast furnace without any further processing.
