Eddy-Current Induced Magnetic Separation of Nonferrous Metals from Solid Wastes

Abstract:

The increasing demand for nonferrous metals in China made the recycle of metallic values such as copper and aluminum metals from solid wastes a prospective resource for nonferrous metals. Eddy-current induced magnetic separation as a friendly separation method may be effectively applied for the separation of nonferrous metals from solid wastes. In the present investigation, a pilot-scale eddy-current induced magnetic separator and its separation procedure was briefly introduced, and the magnetic force acted upon a metal ring is theoretically calculated; on the basis of the calculation of magnetic force, the effects of two key operational parameters, i.e., conductivity/density ratio of metals and frequency of alternative magnetic field, on the separation performance of the pilot-scale magnetic separator were investigated. The results of investigation indicate that the eddy-current induced magnetic separation is effective for the recycle of nonferrous metals from solid wastes.
