Patent ID: 7726493

Claim:
A method for the recovery of non-ferrous metal-comprising particles from a particle stream, yielding a non-ferrous metal-enriched fraction and a non-ferrous metal-depleted fraction, wherein the method comprises the steps of: a) putting the particle stream onto a conveyor belt in the form of a monolayer with a liquid, such that at least the not non-ferrous metal comprising particles will adhere to the conveyor belt at least partly due to the action of the liquid; b) subjecting the moist mono-layer on the conveyor belt to a magnetic field rotating in the same direction as the belt, for the separation of non-ferrous metal-comprising particles which are loosened from the moist mono-layer by the action of the magnetic field, yielding the non-ferrous metal-enriched fraction, and c) removing the particles adhering to the conveyor belt from an underside of the conveyor belt, yielding the non-ferrous metal-depleted fraction.
