The invention discloses a method for extracting aurum in alkali cyaniding enrichment aurum dipping valuable liquid. It includes the following steps: mixing modified tertiary amine extracting agent, modifying agent, and thinner to make organic phase; contacting the organic phase with alkali cyaniding aurum dipping valuable liquid to take extraction to Au(CN)2; taking reverse extraction to the organic phase with reverse extraction solution and transferring aurum cyanogen anionic complex into reverse extraction liquid, the aurum dipping solution would be recycled, and the organic phase after taking reverse extraction would be circularly used. The invention has the advantages of high efficiency, simple technology and energy saving. |
