    27/02/2020· A gas–solid fluidized bed using magnetite particles is an effective methodology for coal beneficiation in the field of dry coal cleaning. Broadening the size range of magnetite used in the bed decreases medium preparation cost. In this study, a tapered fluidized bed was used to investigate a magnetite particle size range of −0.5 + 0.074 mm. The results showed that a tapered fluidized

  • Regular Inspections Prevent Magnetite Losses Coal Age

    Magnetite could be lost in multiple stages of the coal beneficiation process. The drain-and-rinse screens, for example, are trying to wash as much magnetite off the clean coal as possible. If they do not have enough water, however, the magnetite could be lost to the clean coal stream. Ideally, most prep plant operators make sure the sprays on drain-and-rinse screens operate correctly with lots
