· Iron ore is a rock from which the metal iron is extracted. About 98% of the world’s iron is used to produce steel. Pure iron is an element and a soft grayish-white metal. Other than meteorites that fall from the sky, iron is never found by itself in nature. Most iron is part of minerals that contain other elements.

· 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 100% fine product.
