Resourceful treatment method for waste copper-aluminum layered composite material

The invention relates to a resourceful treatment method of a waste copper-aluminum layered composite material, which comprises the following steps: in an inert atmosphere, preserving the heat of the waste copper-aluminum layered composite material to be treated at 660-1080 DEG C to separate copper from aluminum to obtain molten aluminum and copper solid slag; and after acid leaching is conducted on the copper solid slag, solid-liquid separation is conducted, and leachate and crude copper are obtained. According to the method, aluminum and copper are pre-separated to obtain aluminum ingots and copper solid slag, stripping can be achieved without mechanical vibration or end prying, a large amount of aluminum can be recycled firstly, the amount of aluminum entering the acid leaching procedure is effectively reduced, excessive loss of aluminum is avoided, the treatment cost is reduced, and industrial application is achieved. 本发明涉及废旧铜铝层状复合材料的资源化处理方法，于惰性气氛下，将待处理的废旧铜铝层状复合材料在660-1080℃保温，使得铜、铝分离，获得铝液和铜固渣；对所述铜固渣进行酸浸后，固
