| description | The invention provides a comprehensive recovery method for copper smelted slag. The method comprises the following steps: carrying out reductive fuming and settlement on the smelted slag by using a CRfurnace to recover valuable metals in the smelted slag comprehensively; and making harmless slag, wherein the CR furnace comprises a cavity which comprises a reductive fuming cavity and a settlementcavity communicating to each other; the step of recovering the valuable metals in the recovered smelted slag comprises the following steps: carrying out reductive fuming treatment on the smelted slagin the reductive fuming cavity to obtain value metal soot and reduced slag; and settling the reduced slag in the settlement cavity to obtain copper matte and harmless slag; or settling the smelted slag in the settlement cavity to obtain copper matte and settled slag; and carrying out reductive fuming treatment on the settled slag in the reductive fuming cavity to obtain valuable metal soot and harmless slag.
