In order to realize efficient metal recovery,the cyclonic-static microbubble flotation column was used to carry out the semi-industrial test of gold concentrate flotation.The results showed that when the feed grain size of -38 μm accounts for 93 %,the flotation slurry concentration is 25 %-27 %,the feeding rate is 400 kg/h,the rough-ing reagent regime conform to field production,and no additional agents are added in scavenging,the once roughing-once cleaning-once scavenging closed-circuit test are carried out,obtaining the concentrates with gold recovery rate of 97.33 %,silver recovery rate of 96.32 %,lead recovery rate of 98.03 %,zinc recovery rate of 86.36 %,copper recovery rate of 97.27 % and sulfur recovery rate of 95.51 %.The indexes are good and better than field production.
