A high field helical flow slurry separator was constructed to concentrate weakly magnetic ores with a magnetic moment about the value of hematite. The process is to flow the slurry helically around a current-carrying conductor in a cylindrical annulus. The magnetic field gradient forces magnetic particles inwards while nonmagnetic particles are deflected outwards by centrifugal force. Separation occurs at the exit end of the channel by a divider that separates inboard from outboard slurry. The separator performance was studied both theoretically and experimentally. A universal theoretical model was developed based on turbulent diffusion in cyclones. The model is in good agreement with experimental data.
