The main ores of iron usually contain Fe2O3 (70 % iron, hematite) or Fe3O4 (72 % iron. magnetite). Ores are normally associated with unwanted gangue material.What Is Iron Ore Beneficiation? (with pictures),Iron ore mining often focuses on looking for hematite deposits known as red iron ore, and magnetite, as they have naturally weak magnetic fields that aid in their purification. Hematite, however, responds better to the flotation process in iron ore beneficiation than magnetite, so it is the preferred type of ore.BENEFICIATION OF IRON ORE - nitrkl.ac.in,Hematite is weakly magnetic, but it has a variety called magnetite which is found in many ore bodies in minute quantities having magnetic properties closely related to those of magnetite. The content of iron in the ore and physical characteristics
