Iron Recovery from Hematite Tailings by a Novel HGMS-Centrifuge Process

Abstract:

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 high-grade iron concentrate, then this concentrate is cleaned with a continuous centrifugal concentrator to produce a high-grade iron concentrate. The results of investigation indicate that this novel process is capable of producing an iron concentrate assaying 58.48% Fe with 21.66% recovery from the tailings assaying 28.12 % Fe. It was concluded that this novel process may be effectively used to recover iron values from low-grade hematite tailings.
