The low-grade iron ore generally contains goethite as the major iron phase mineral and kaolinite and other minerals as gangue minerals. During the beneficiation of low-grade iron ore, a lot of fines were generated during different unit operations. These fines report to the tailing pond for the settling of the particles.
