Beneficiation: Once the iron ore is extracted, it needs to be processed to remove impurities and increase its iron content. This process, known as beneficiation, involves crushing, screening, washing, and magnetic separation or flotation to separate the iron ore from other minerals and impurities. Beneficiation processes can vary …

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. 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.
