2016-5-15 · An early separation into two streams (concentrate or loss to tailings) can be seen for certain runs of the hematite tracers. Tracers speeds and radial position from the centre of the spiral give more details about the presence of the slurry film''s secondary flow in the middle zone of the spiral trough.Potential Applications for Dry Beneficiation of Iron Ore ...Hematite/magnetite plants in this region typically use spirals as the primary separation process and also incorporate Low Intensity Magnetic Separation steps (LIMS). A common issue across hematite/magnetite plants is the recovery of fine iron as the iron tailings amounts often reach levels as high as 20%.
