The　use　and　scrap　of　cemented　carbide,　especially　WC-Co　series　cemented　carbide,　are　increasing　every　year.　Recycle　of　cemented　carbide　scrap　is　paid　attention　to　more　and　more　by　researchers.　In　this　paper,　the　molten　salt　electrolysis　method　was　employed　to　extract　tungsten　and　cobalt.　The　focal　points　of　this　study　were　the　electrochemical　dissolution　mechanism　of　WC-Co　two-phase　scraps　and　the　treatment　process　of　multiple　pieces　of　WC-Co　scrap.　Electrochemical　impedance　spectroscopy　indicated　that　the　dissolution　mechanism　of　WC-Co　composite　had　the　anodic　potential　dependence.　The　equivalent　circuit　model　of　WC-Co　two-phase　composite　can　adopt　the　＂R-ct　parallel　model＂　of　cobalt　and　tungsten　carbide.　M　the　case　of　surface　area　evolution　or　multiple　anodes　electrolysis,　the　equivalent　circuit　model　can　also　adopt　the　＂R-ct　parallel　model＂,　which　built　a　bridge　between　single　WC-Co　anode　and　multiple　WC-Co　anodes.　Consequently,　we　designed　and　achieved　the　recovery　process　of　multiple　WC-Co　anodes.　The　XRD　analysis　and　elemental　analysis　showed　that　the　products　were　pure　cobalt　and　pure　tungsten,　respectively.
