Abstract

Results of processing the metallic sulfide ore show that the rough concentrate and rich middling of tin can be obtained both by the two combined processing flowsheet of flotation-gravity concentration and gravity concentration-flotation.The total recovery of tin reaches 61.81%~(67.90%),and the rough copper concentrate of 5.22%~7.04%Cu can be obtained with a recovery of 70%~78% too.In these ways,comprehensive utilization of the resource can be realized well.The combined processing flowsheet of flotation-gravity concentration with stage grinding and stage separation is better than the another flowsheet.
