A　gallium　concentrate　with　more　than　0.1%　Ga　can　be　obtained　by　＂roasting-sulfuric　acid　leaching-and　precipitation＂　process　from　alunite　concentrate.　In　order　to　realize　the　high　value　utilization　of　gallium　concentrate,　the　technology　of　recovering　metal　gallium　by　＂alkali　leaching-ion　exchange-solution　purification-electrowinning＂　was　proposed,　and　the　optimum　technological　conditions　were　studied.　Under　the　optimum　conditions,　the　leaching　rate　of　Ga　in　gallium　concentrates　reaches　98.46%.　The　ion　exchange　experiment　shows　that　the　D5240　resin　can　effectively　enrich　Ga,　but　the　impurity　vanadium　is　also　enriched.　The　desorption　solution　contains　gallium　2.1　g/L　and　vanadium　0.23　g/L.　Vanadium　can　be　removed　by　the　calcium　salt　method　under　the　condition　of　pH=12.　When　the　Ca　2+　additive　amount　is　0.02　mol/L,　the　vanadium　concentration　is　reduced　to　1.45　mg/L.　The　current　efficiency　in　gallium　electrodeposits　increases　firstly　and　then　decreases.　When　the　electrodeposition　time　is　2　h,　the　current　efficiency　reaches　4.3%　of　the　peak　value.　With　the　increase　of　NaOH　concentration　in　the　electrodeposition　electrolyte,　the　cathode　surface　is　from　coarse　to　smooth.　Finally,　the　purity　of　99.94%　metallic　gallium　is　obtained.　©　2018,　Science　Press.　All　right　reserved.
