Aiming at the problems of high oxidation rate, high content of slime and high consumption of collector (butyl xanthate) for the copper-cobalt oxide ore from the Democratic Republic of the Congo, experimental researches were carried out with an auxiliary collector (MC-07) in its flotation process. The results show that at the stage of copper oxide ore flotation, with butyl xanthate as a single collector at a total dosage of 400 g/t, the concentrate is produced totally with a copper recovery of 78.41% and a cobalt recovery of 38.93%; while by using the conventional collector of butyl xanthate in combination with an auxiliary collector of MC-07, at the dosage of 99 g/t and 33 g/t respectively, the concentrate is finally produced totally with a copper recovery of 78.76% and a cobalt recovery of 39.30%. It is shown that small additions of auxiliary collector of MC-07 can reduce the dosage of butyl xanthate with the similar technical indicators.
