Once the deposit of iron ore is feasible, the mining process is moved to digging the ore out from the earth. The most widely used technique is open-pit mining, which involves drilling and blasting the surface rock and soil to get to the ore deposit beneath it in states like Minnesota and Michigan, around the area of Lake Superior.

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. Yield from the plants has been ...
