Abstract
The applicability of high gradient magnetic separation (HGMS) for the removal of heavy metals from mixed solutions of para- and diamagnetic ions (nickel and zinc) was studied. The heavy metals were precipitated as phosphates by the addition of Na3PO4. The susceptibilities of the precipitations showed the expected linear dependence with respect to the mass fraction of nickel. However, the separation experiments with a 1.8 Tesla magnetic separator demonstrated that even small fractions of nickel result in separation efficiencies comparable to those of pure nickel phosphate. The experimental results were compared with theoretical filter calculations based on deep filter theories and single wire models.
