Formatted abstract
In conventional practice primary lead production is carried out in a lead blast furnace using sinter feed. At the Yunnan Metallurgical plant the ISASMELT furnace is used to produce lead bullion and a high-lead slag from lead concentrate. The high-lead slag is cast into lumps to provide a suitable feed for the blast furnace. In the present study the relative microstructures and reduction characteristics of industrial lead sinters and synthetic lead slags in CO/CO2 gas mixtures have been measured and compared. The microstructure and property changes and the mechanisms of reduction in each case are examined and discussed. The results of the study are used to explain the successful implementation of cast slag feed in a commercial ISASMELT-lead blast furnace practice. © Canadian Institute of Mining, Metallurgy and Petroleum.
