The　recycling　of　WC-Co　hard　metal　scraps　has　been　taken　into　consideration　in　the　literature,　due　to　the　release　of　toxic　substances　and　long　recovery　process.　In　this　study,　the　recovery　of　tungsten　process,　based　on　the　molten　salt　electrolysis　treatment　of　WC-Co　hard　metal　scraps,　was　developed.　The　anode　polarization　curves　were　applied　to　investigate　the　dissolution　of　the　WC-Co　hard　metal　scrap.　Then,　the　electrochemical　behavior　of　tungsten　and　cobalt　ions　dissolved　from　WC-Co　scrap　anode,　was　studied　by　cyclic　voltammetry　(CV)　and　square　wave　voltammetry　(SWV).　The　results　demonstrated　that　the　reduction　of　tungsten　and　cobalt　ions　occurred　through　a　one-step　process　involving　the　transfer　of　two　electrons.　This　process　was　achieved　by　the　diffusion　of　tungsten　and　cobalt　ions　in　the　melts.　Finally,　the　parameters,　such　as　the　electrolysis　current,　the　electrolysis　duration　and　temperatures,　were　applied　to　analyze　the　effect　of　different　electrolysis　conditions　on　the　composition　of　recycled　products.　The　results　demonstrated　that　the　electrolysis　current　and　the　electrolysis　temperature,　compared　to　electrolysis　duration,　have　significant　effects　on　the　selectivity　of　tungsten　recycling.　Furthermore,　the　analysis　of　cathode　products　demonstrated　that　a　tungsten　powder　of　approximately　500　nm　could　be　selectively　recovered　from　WC-Co　hard　metal　scrap　with　the　electrolysis　condition　of　60　mA　for　4h　at　1073　K　in　NaF-KF　molten　salt.　(C)　2018　Brazilian　Metallurgical,　Materials　and　Mining　Association.　Published　by　Elsevier　Editora　Ltda.
