Abstract
The invention relates to a method for the recovery of non-ferrous metal-comprising particles from a particle stream. According to the invention, the particle stream is put onto a conveyor belt in the form of a monolayer such that with the aid of a liquid, at least the non-ferrous metal comprising particles will adhere to the conveyor belt, and the mono-layer is subjected to a magnetic field rotating in the same direction as the belt, for the separation of non-ferrous metal-comprising particles, yielding the non-ferrous-enriched fraction, and subsequent to which the metal particles that are not nonferrous adhering to the conveyor belt are removed, yielding the non-ferrous metal-depleted fraction.
Claims6
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.
