Sintering is the most extensively used and economic agglomeration process to prepare iron ore fines for blast furnace use. Granulation is the most critical factor controlling iron ore sintering process, as it improves sinter mix permeability. Currently, sinter plants are receiving significant proportion (up to 40%) of − 150 μm micro-fines in …

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.

The final stage in iron ore processing is ironmaking, where the iron ore is transformed into molten iron through a process called reduction. The most common method of ironmaking is the blast furnace route. In a blast furnace, iron ore, coke (carbon), and fluxes (limestone or dolomite) are loaded into the furnace from the top.
