Technology Research for Processing Refractory Oxidized Copper ore by Sulphidizing Flotation
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.
