Iron Recovery from Hematite Tailings by a Novel HGMS ...

During the processing of iron ores, a large quantity of low-grade tailings containing abundant iron values in fine particle size range is produced. A novel HGMS-Centrifuge process is proposed to recover iron values from a low-grade hematite tailings. In this process, the tailings is effectively roughed with pulsating high pulsating high gradient magnetic separator to produce a relatively …
