A copper smelting slag comprehensive recovery method and device. Said method uses a CR furnace to perform reductive fuming and settling on the smelting slag to comprehensively recover valuable metals in the smelting slag and produce harmless slag. The CR furnace (30) comprises a cavity, the cavity comprising a reductive fuming cavity (31) and a settling cavity (32) in communication with each other. Recovery of valuable metals in the smelting slag comprises the steps of: performing a reductive fuming treatment on the smelting slag in the reductive fuming cavity (31) to obtain valuable metals-containing smoke dust and reduced slag, and performing a settling treatment on the reduced slag in the settling cavity (32) to obtain copper matte and harmless slag; or performing a settling treatment on the smelting slag in the settling cavity (32) to obtain copper matte and settled slag, and performing a reductive fuming treatment on the settled slag in the reductive fuming cavity (31), so as to obtain valuable metals-co
