Abstract/Summary A comprehensive research program on the characterization of zinc and lead smelting slags and sinters has been undertaken. The research combines experimental and thermodynamic modeling studies of the system PbO-ZnO-FeO-Fe2O3-CaO-SiO2-Al2O3. Experimental measurements of the liquidus and solidus have been undertaken under oxidizing and reducing conditions using equilibration, quenching, and electron probe X-ray microanalysis, The experimental data obtained have been used for thermodynamic model development as well as for pseudo-ternary liquidus diagrams which can be used directly by process operators. The thermodynamic modelling has been carried out using the computer system FACT which contains thermodynamic databases for over 5000 compounds as well as evaluated solution models. A new optimization has been carried out which significantly improves the predictive ability of the thermodynamic model for lead and zinc smelting processes. Examples of experimentally determined and calculated liquidus diagrams are presented. These examples provide information of direct relevance to various lead and zinc smelting processes including the lead blast furnace, ISP and lead smelting.
