[PDF] Utilization of Microfines in Iron and Steel Making

A huge quantity of iron ore fines (60 % of ore) is generated during production of lump ore. Moreover, iron oxide fines are generated in different units of steel plants such as blast furnace, LD converter, mills etc. Coarser sizes of these are used in sinter plant. However in sintering, there is some restriction of using microfines. It is possible to use in pelletization, but pelletization is a

Iron ore Wikipedia

Lower-grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high-quality fine ore powders, are known as fines. Magnetite. Magnetite is magnetic, and hence easily separated from the gangue minerals and
