Waste slag from steelmaking industries using titanomagnetite sands can contain up to 30 wt.% titanium and is available in its molten state at approximately 1750 K. As the use of high temperature electrolytic processes for the production of Ti from pure TiO2 and metals from molten oxides have already been proven, we are investigating if the ultra-high temperature electrolytic production of titanium from waste slag is feasible. However, knowledge of the underlying electrochemistry is limited as there is scarce information on the properties of the slag relevant to molten oxide electrolysis (e.g. ionic vs electronic conductivity, viscosity, phases present). Hence, significant experimentation is required, specifically, we present the characterization of the electrode products and discuss the materials and processing conditions required to overcome the challenges resulting from electrolyzing complex slags mixtures at ultra-high temperatures.
