Abstract
In the classical pyrometallurgy route for lead smelting , the smelter produces a slag containing measurable quantities of lead . The lead in the slag is most often discharged from the smelter, leading to the disposal of significant quantities of lead . The slag needs to be safely stored to prevent the release of lead into the environment. In this work, the recovery of lead , and other deleterious elements, from a lead smelter slag has been investigated experimentally. Thermodynamic simulation was performed to determine the viability of a methane reduction process. Based on the thermodynamic simulation and knowledge of the phases and distribution of elements between the phases in the smelter slag, methane reduction was tested on a bench scale. A comparison between the thermodynamic predictions and observations provides an insight into the processes occurring during reduction and the kinetic limitations of this process.
