Recovery of non-ferrous metal particles from e.g. waste streams involves adhesion of stream as a mono-layer to conveyor belt using water and subjecting the moist mono-layer to magnetic field rotating in the same direction of the belt

摘要

Recovery of non-ferrous metal particles from a stream to yield non-ferrous metal-enriched and metal depleted fractions involves putting the stream onto a conveyor belt (1) as a mono-layer such that with the help of water at least the non-ferrous metal particles get adhered to the belt; subjecting the moist mono-layer to magnetic field rotating in the same direction of the belt for the separation; and removing the adhered particles.
