In　this　work,　the　electrochemical　behavior　of　cobalt　ion　was　investigated　using　an　inert　graphite　rod　electrode　at　1073　K　in　NaF-KF-CoF2　(1　wt%)　molten　salt　system.　Several　transient　electrochemical　techniques,　such　as　cyclic　voltammetry,　square　wave　voltammetry,　and　chronopotentiometry,　were　used.　Results　showed　that　electroreduction　of　Co2+　to　Co　is　a　reversible,　one-step,　two-electron　transfer.　The　diffusion　coefficient　of　Co2+　was　investigated　with　cyclic　voltammetry,　square　wave　voltammetry,　and　chronopotentiometry,　and　results　from　the　considered　methods　exhibited　fair　agreement.　Electrodeposition　of　cobalt　was　performed　at　-0.3　V　versus　Pt　at　1073　K　for　4　h　in　a　NaFKF-CoF2　(1　wt%)　melt.　The　deposits　were　examined　using　X-ray　diffraction　and　X-ray　fluorescence,　and　results　confirmed　the　obtained　deposits　as　metallic　cobalt.　The　present　study　aims　to　provide　a　theoretical　reference　for　electrolysis　of　WC-Co　hard　metal　scraps　in　molten　salt.
