Tungsten　was　extracted　from　LiCl-KCl-Li2WO4　molten　salt　with　tungsten　carbide　as　soluble　anode,　and　its　electrochemical　dissolution　was　studied.　Although　the　fused　salt　electrochemical　method　has　the　advantages　of　short　process　and　easy　equipment　operation,　the　current　electrolysis　process　faces　problems　such　as　higher　electrolysis　temperature,　high　energy　consumption,　and　complex　composition　of　the　products.　Therefore,　in　this　study,　in　order　to　reduce　the　electrolysis　temperature　and　energy　consumption,　tungsten　was　extracted　by　LiCl-KCl-Li2WO4　molten　salt　system　in　the　temperature　range　400　degrees　C-600　degrees　C.　In　addition,　compared　to　the　blank　salt　electrolysis,　the　addition　of　Li2WO4　as　the　active　material　facilitated　the　reaction　and　improved　the　dissolution　efficiency,　and　the　current　efficiency.　Through　a　series　of　electrochemical　tests,　it　is　proved　that　the　adding　of　Li2WO4　decreases　the　charge　transfer　resistance　and　speeds　up　the　reaction.　Moreover,　the　oxidation-reduction　process　of　tungsten　ion　in　tungstate　was　investigated,　indicating　that　the　redox　process　is　a　reversible　process　controlled　by　diffusion.　Clusters　of　spherical　tungsten　powders　were　prepared　at　500　degrees　C　by　optimizing　the　experimental　parameters.
