Processes for Beneficiation of Iron Ores. Iron is an abundant element in the earth's crust averaging from 2 % to 3 % in sedimentary rocks to 8.5 % in basalt and gabbro. Because iron is present in many areas, it is of relatively low value and thus a deposit must have a high percentage of metal to be.
