METHOD FOR RECOVERING METALS FROM ELECTRONIC WASTE CONTAINING PLASTICS MATERIALS
First Claim
1. A method for treating materials containing a mixture of plastic and metal materials, said method comprising:
- shredding the materials to be processed;
pyrolysis of the shredded material;
a first magnetic separation performed on the pyrolyzed materials, providing a ferrous metal fraction and, secondly, non-ferrous residues;
a second magnetic separation performed on the non-ferrous residues, providing, on the one hand, a non-ferrous metal fraction and, on the other hand, non-magnetic residues containing precious metals.
