Molten oxide electrolysis has the potential to be a more efficient method to produce metals with near zero CO2 emissions compared to traditional methods. If metals can be produced from industrial by-products, such as steelmaking slags, then the environmental and sustainability benefits are considerable. In previous work, we demonstrated the reduction of Ti from a pseudo-quinary metal oxide melt. That showed that ionic transport in the melt was sufficient without the addition of a salt, such as the calcium chloride required for the FFC Cambridge process. In this work, we demonstrate that Ti can be reduced from sodia-titania melts under conditions predicted by FactSage. This operating window would not be predicted using ideal solution models. Based on this work, we discuss the characteristics of high temperature electrolytic melts that allow for the extraction of metals.
