Zusammenfassung:The main objectives of blast-furnace operators include maximum production of pig iron of required chemical composition at minimal cost. This can be ensured only in case of quality raw material basis and trouble-free operation of blast-furnace. Both parameters are influenced by the concentration of undesirable elements. The negative elements contained in the blast-furnace raw materials cause many technological problems in the sintering as well as in the blast-furnace process. These are mainly heavy metals and alkaline carbonates. The article deals with the analysis of material balance of zinc and selected alkaline carbonates contents in the input raw materials and output products of the blast-furnace.
