Lead Oxide and Lead-containing Slag/Glass Reduction Using Hydrogen

The current study highlights the potential of decarbonisation of the lead metal industry by utilizing hydrogen reduction in processing and recycling lead-containing slag. This study emphasizes the current limited understanding of hydrogen's role as a reductant in reducing lead-containing slag, particularly in the context of complex industrial metal production slags. The study aims to address this knowledge gap by conducting a systematic investigation, ranging from simple (PbO) to complex slag systems (PbO-SiO2, PbO-SiO2-CaO, and PbO-SiO2-CaO-Fe2O3). The focus is on understanding the thermodynamics, kinetics, and mechanisms involved in the hydrogen reduction of these systems, supported by detailed materials characterization.
