Abstract
The authors have studied the use of the cryomagnetic separation techniques for the processing of non-ferrous waste since 1989. This paper presents: – the superconducting magnetic separator and the adapted processing installation; – the main results achieved by tests with synthetic and industrial effluents containing Ni, Cr, Zn, Cu or V. The research work confirmed the assumption that a cryomagnetic separation can be applied to non-ferrous waste materials. Technical difficulties of implementing this technique are understood. A patent containing the innovative process seems to be ofcommon interest for the processing of fluids charged with small amounts of dissolved metals. As a result of the investigations such an installation appears to be a new way to extract metals from fluids before they are discharged into nature. This is important in view ofmore stringent controls in the future.
