In working with industrial partners around the world, we are able to provide economic and ecological solutions for the treatment of their by-products, residues and wastes containing non-ferrous metals. Our work often begins when others have finished theirs. Our feed materials are effectively comprised of residues generated by the industrial activities of our suppliers and clients. These arrive in the form of fumes, drosses, slags, sludges, dusts, ashes, cements, filter cakes, spent catalysts, complex alloys, turnings, grindings, manufacturing rejects etc….. The complex non-ferrous metals residues that we treat, and which contain Cu, Zn, Pb, Sn, Cd, Se, Te, Ni, Co, In, Ag, Au (and others) arrive from all over the world. We convert them into more simple, purer metal containing cements, salts or concentrates, both in solid form and in solution, and which become feed materials themselves for plants in the metallurgical or chemical industries. |
