The basic forms of the three-stage crushing process are: three-stage open circuit and three-stage one closed circuit. The three-stage open circuit process is used to process argillaceous iron ore with high water content and large and medium-sized iron ore concentrators that are prone to produce a large amount of quartz dust ore.

India possesses vast reserves of iron ore. All the ex-isting iron and steel plants in the country utilize hemati-tic ores, though a few deposits of magnetite are also being considered for utilization. Until very recently only hand-mining was employed to prepare iron ore of uniform size and composition for smooth blast-furnace operation. The ore ...

Dry processing of iron ore: In dry processing of iron ore, ROM is generally crushed below 40 mm through three-stage crushing and thus segregated by screening into 10–40 and −10 mm fractions. For softer ore, tumbler index is generally low and hence lump ore is crushed below 10 mm to produce fine product.
