| Abstract: | In view of the occurrence state of copper minerals and dissemination size of a copper sulfide gold ore with Cu grade of 3.27% and Au grade of 2.35 g/t, flotation technique was studied. With the optimized grinding fineness of -0.074 mm 70%, at pH value of around 8.5, by adopting a combined collectors of BY-309 and B-5050 with the dosage of 110 g/t and 55 g/t, respectively, a copper-gold bulk concentrate graded at 18.87% Cu and 13.587 g/t Au, with Cu and Au recovery of 92.70% and 89.53%, respectively, can be obtained adopting a closed-circuit flowsheet consisting of one stage of roughing, three stages of cleaning and three stages of scavenging. Therefore high efficient comprehensive recovery of copper sulfide gold ore was realized. |
