Abstract: To recover the zinc oxide mineral from the tailing of Huili Zinc Concentrator and in view of the high slime content of the tailing, laboratory test was made on the process consisting of desliming by tabling, desulfuration-floatation and sulfidization-flotation of zinc oxide mineral using a new type efficient collector ZP-50. As a result, a zinc oxide concentrate grading 36.04% with a recovery of 57.58% was obtained.
