| Abstract: | In this paper, aiming at the extraction residual solution produced by the Ga-Ge-Cu comprehensive recovery system, the production process flow for producing basic zinc carbonate, active zinc oxide by high-temperature calcination and anhydrous sodium sulfate by one-step method is designed through neutralization oxidation impurity , zinc powder replacement of copper and cadmium, cobalt and nickel removal by organic reagent. The extraction residual solution of Ga-Ge-Cu is effectively separated and enriched to produce valuable enriched slag and industrial products, thus further improving the economic benefits of comprehensive recovery. |
