The invention discloses a dressing and smelting processing method for a copper-cobalt oxide ore containing easy-floating gangue. The dressing and smelting processing method comprises the steps that araw ore is subjected to ore grinding to obtain raw ore pulp; an easy-floating gangue collector is added into the raw ore pulp, and roughing of the easy-floating gangue is performed to obtain a froth product and first flotation tailings; an easy-floating gangue inhibitor, a copper-cobalt oxide ore regulator and a copper-cobalt oxide ore collector are sequentially added into the froth product to perform copper-cobalt oxide ore roughing and copper-cobalt oxide scavenging to obtain a low-quality copper-cobalt oxide rough concentrate; the easy-floating gangue inhibitor is added into the low-qualitycopper-cobalt oxide rough concentrate for copper-cobalt oxide concentration to obtain a high-quality copper-cobalt oxide rough concentrate; and the high-quality copper-cobalt oxide rough concentrateis mixed with the first flotation tailings, and then H2SO4 is added for stirring and leaching to obtain copper-cobalt oxide ore leaching ore pulp. The dressing and smelting processing method can effectively remove easy-floating gangue minerals in the copper-copper oxide ore, and solves the problem that the easy-floating gangue minerals seriously interfere with the whole leaching process.
