Valorisation of steel works wastes containing Zn, Pb and ferrites hydrometallurgy

Ziel

The suggested hydrometallurgical process which has been tested on the laboratory scale provides a complete treatment for steel works dust. It is based on a new concept of selective lixiviation of zinc and lead in a basic environment, with an acid treatment of the insoluble residues, with the aim of reusing them in the form of mixed iron oxides or recycling in the steel industry. The process would thus produce no waste by-products.
