Iron ore is essential in steel making; however, high-grade ores have diminished, making low-grade ores inevitable. These low-grade iron ores need further beneficiation to upgrade the iron content. Currently, traditional physical and chemical methods are utilized and are not environmentally friendly. Bio-beneficiation techniques …

Gravity separation methods include heavy media, jig, and shaking table beneficiation. Before gravity separation, the manganese ore is first crushed (6-0mm or 10-0mm) and then classified. The coarse-grained manganese ore particles enter the jig for sorting; the fine-grained ore particles are sent to the shaker for sorting.
