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. Yield from the plants has been ...
