Abstract

Slag from the smelting of lead can contain up to twenty per cent zinc as an oxide. An understanding of the lead smelting process and of the subsequent fuming process for the recovery of zinc is enhanced by a knowledge of the activity coefficient behaviour of zinc oxide in smelting slags. The literature presents a wide range of contradictory values. This paper critically reviews the published data and outlines new measurements being made by the authors. A consistent set of zinc oxide activity coefficient data is presented for liquid slags within the ZnO-'FeO'-CaO-Al2O3-SiO2 system, through a combination of present and previous measurements.
