The iron and steel metallurgy produces significant quantities of solid, liquid and gaseous wastes. The solid wastes like dusts, sludges and mill scales have been stored in dumping area due to their chemical composition, mainly by high content of zinc, cadmium, lead or organic compounds contamination. There are an alternative to waste disposal such as pyrometallurgical or hydrometallurgical processes for separation of iron and heavy metals. The paper presents the other possibility of utilization these wastes in non ferrous metallurgy, specifically in lead recycling technology. Investigations were carried out on effective utilization of iron together with non ferrous metals.
