Zusammenfassung:The activation effects of single activator and some combined activators on Yunnan copper oxide ore were studied with Drawing a conclusion that the best activation - xanthate flotation result could be obtained by using sodium sulfide and ethylenediamine phosphate as the combined activator. on this basis, the open and closed circuit flotation tests were done , and in the closed circuit flotation test ,the flotation concentrate with yield of 5.90%, copper grade of 16.01% and recovery of 74.38% was obtained
