This　study　was　performed　to　improve　the　associated　gold　recovery　from　Zijinshan　gold-copper　mine.　The　depressant　sulfide　and　flotation　copper　technology　was　used　in　the　processing　of　quickly　flotation　and　first　rougher　flotation.　The　present　work　was　aimed　to　improve　the　gold　recovery　rate　and　not　affect　the　copper　recovery　by　adjusting　the　pulp　density,　adding　collector　BP　and　depressor　HY.　In　the　conditions　of　the　pH　value　10.5,　dithiophosphate　25g/t,　BP　14g/t,　2#　oil　3g/t　and　the　HY　25g/t,　the　recovery　of　copper　and　gold　can　reach　85.02%　and　52.50%,　respectively.　So　this　processing　could　improve　the　recovery　rate　of　copper　and　gold　efficiently,　and　the　aim　for　increasing　the　gold　recovery　was　achieved.
