Abstract: In order to efficiently and comprehensively recover a carbon-containing lead-zinc refractory ore in Anhui，an experimental study was conducted on the ore based on the study of ore properties. The results show that the lead concentrate with lead grade of 55.35% and lead recovery of 94.76%，the zinc concentrate with zinc grade of 55.46% and zinc recovery of 91.98%，and the sulfur concentrate with sulfur grade of 43.55% and sulfur recovery of 70.90% were obtained by adopting the lead-zinc preferential flotation process. The optimal flotation process was determined for the recovery and utilization of the ore.

Key words: flotation, carbon-bearing lead-zinc ore, separation of lead and zinc
