However the fines, slimes and tailings generated in the process of beneficiating these low grade iron ores contains good amount of iron values. These iron values can be recovered by further beneficiating the fines, slimes and tailing by selective flocculation, which is defined as the selective agglomeration of iron ore particles using …

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.
