The principal separation in iron ore beneficiation, therefore, is between the iron minerals, hematite and/or magnetite, and silica, principally in the form of quartz (SiO 2). The use of flotation, either alone or in combination with magnetic separation, has been well established as an efficient method for rejecting silica from these iron ores.

Almost 100% of mined iron ore is used in steel production, making it essential for everything from staples to buildings. Beneficiation is the term for reducing the size of valuable iron ore particles and separating them from the gange (unusable minerals), which are then discarded. There are several different methods of wet and dry separation.
