With　the　widespread　expansion　of　titanium　applications　and　its　significant　increase　in　usage,　the　issue　of　recycling　titanium　resources　after　consumption　has　emerged.　Focusing　on　titanium　alloys　with　high　usage,　such　as　TC4　(Ti-6Al-4V),　this　article　proposes　a　titanium　separation　and　recovery　method　based　on　molten　salt　electrolysis.　This　method　thoroughly　analyzes　the　characteristics　of　elements　in　TC4　and　electrochemical　principles,　ensuring　that　vanadium　in　the　TC4　alloy　does　not　undergo　electrochemical　dissolution　when　the　electrolysis　potential　is　below　0.3　V　vs　Pt.　Subsequently,　through　electrochemical　analysis,　it　was　discovered　that　the　precipitation　of　aluminum　ions　is　influenced　by　concentration.　Therefore,　by　controlling　the　concentration　of　aluminum　in　the　eutectic　molten　salt,　such　as　increasing　the　electrolyte　concentration　and　shortening　the　electrolysis　time,　the　precipitation　of　aluminum　can　be　effectively　avoided.　Under　the　experimental　conditions　mentioned　above,　vanadium　elements　deposit　at　the　bottom　of　the　crucible　in　the　form　of　anode　slime,　while　aluminum　dissolves　and　remains　in　the　electrolyte.　Meanwhile,　titanium　ions　in　the　cathode　region　undergo　electron　reduction　and　deposit　in　the　cathode　area　in　the　form　of　titanium,　thus　achieving　precise　separation　of　alloy　elements.　Experimental　verification　shows　that　the　purity　of　the　obtained　titanium　reaches　99.17　atomic　percent.　Therefore,　this　molten　salt　electrolysis　method,　which　combines　the　physical　properties　of　alloy　elements　with　electrochemical　principles,　not　only　provides　a　new　perspective　for　the　separation　and　recovery　of　titanium　and　other　critical　metals,　but　also　offers　new　research　directions　for　the　recovery　technology　of　other　alloy　elements.　©　2024　Elsevier　B.V.
