Abstract: According to the oxided copper ore with above 93% oxidizing tatio in Yunnan province, through a variety of measures, such as sulphidization by multi-stage addition of sodium sulfide, sulphidizing flotation of time division, controlling sodium sulfide dosages, and the time of sulphidizing flotation, carried on a serial flotation test in laboratory. The comprehensive grade of copper reaches to 14.52% through the experiment, the recovery rate reaches to 72.29% in Copper concentrate; the comprehensive grade of silver reaches to 366.7 g/t, the recovery rate reaches to 48.07% in silver concentrate, get a good beneficiation technical indicators, and provid the reasonable Science references for similar mines in dealing with copper ores.

Key words: Refractory oxidized copper ore, High oxidation rate, Ulphidizing flotation
