In this study, we reduce TiS2 to Ti via both calciothermic reduction and electrolysis in a CaCl2 melt. Upon calcium reduction at 1133 K in CaCl2 melt, the concentration of sulfur decreases to 0.03 mass% S when an amount greater than twice the stoichiometric calcium amount is added. Upon electrolysis reduction at 1173 K in CaCl2-CaS melt, the concentration of sulfur initially decreases significantly to 0.01 mass% S when a sufficiently large amount of electric charge is supplied. Our results indicate that it is possible to achieve sulfur removal via both calciothermic reduction and electrochemical reaction.
