|On-Site Speaker (Planned)
Low-cost clean primary production of magnesium metal is important for its use in many applications, from light-weight structural components to energy technologies. Recently there has been renewed interest in MgO molten salt electrolysis with a reactive dense liquid metal cathode. This presentation will describe developments in this technology including techno-economic analysis, experiments with carbon and zirconia solid oxide membrane anodes, and new gravity-driven multiple effect thermal system (G-METS) distillation technology. It will also discuss cradle-to-gate life cycle analysis of magnesium metal production using this MgO reduction technology under several raw material and process technology scenarios, including effects of different raw materials, drying and calcining methods, molten salt compositions, electrolysis anode types, and distillation methods.
