Abstract: A novel bis-ligand chalcopyrite collector and a preparation method and application thereof. The collector is prepared by first synthesizing an intermediate oxalyl diisothiocyanate from oxalyl chloride and thiocyanate, and then reacting the intermediate with an amine or an alcohol using a one-pot method. The collector provided by the present disclosure can form more stable dual-site adsorption on the chalcopyrite surface, thereby generating a more stable double-chelate-ring structure than the single-site adsorption of a traditional chalcopyrite collector such as xanthate and dithiophosphate. The collector not only has higher collection ability and excellent selectivity, but also can achieve efficient copper-sulfur separation even under a low-alkalinity condition. The preparation process of the collector is simple and operable, facilitating the flotation of chalcopyrite and its separation from pyrite.
