Development of a new metallurgical process for the production of valuable metallic and mineral materials from by-products generated by the steel industry and other major activity sectors

The zero-waste pilot plant was erected in Vitkovice (Ostrava, CZ) and 9 test campaigns have been performed to date (January 2004). The feasibility of the process with various by-products from carbon and stainless steel production, and from other important activity sectors (power plants, car dismantling companies) was positively assessed. Two different mineral products have been produced according to targets: clinker substitutes for cement production and metallurgical powders for secondary metallurgy. Attractive economic figures were calculated, especially for the treatment of stainless steel by-products.
