| titleOfInvention | Treatment method of copper anode slime copper separating liquid |
| abstract | The invention discloses a method for treating copper anode slime copper separating liquid, which comprises the following steps: adding the copper anode slime copper separating liquid into a cyclone electrolysis device for first-stage cyclone electrolysis, and taking out a first-stage cathode product after the copper anode slime copper separating liquid reaches the electrolysis end point; continuing to perform second-stage cyclone electrolysis, and taking out a second-stage cathode product after the electrolysis end point is reached; and continuing to perform the third-stage cyclone electrolysis, taking out a third-stage cathode product after the electrolysis end point is reached, and collecting the electrolyzed liquid. The method carries out cyclone electrolysis step recovery on the copper anode slime copper separating liquid, uses high current density to generate active copper powder at the cathode through first-stage cyclone electrolysis, directly replaces tellurium in the solution to obtain copper telluride slag, efficiently enriches tellurium, and simultaneously avoids the influence of tellurium on subsequent copper electrolysis; the cathode copper product obtained by the second-stage cyclone electrolysis reaches the specification of national standard cathode copper; arsenic is effectively solidified in the black copper slag through the third-stage cyclone electrolysis, so that the deep recovery of copper is realized, and the impurity removal and the cyclic utilization of the solution are realized. |
