Beschreibung
Zusammenfassung:The invention discloses a zinc electrodeposition and anode mud cleaning method, which specifically comprises the following steps: feeding a mixed electrolyte prepared by mixing a new solution and an electrodeposition waste liquid into an electrodeposition cell for low-concentration electrodeposition to separate out 2-3g/L Zn, and discharging the electrodeposition waste liquid after the electrodeposition is completed, with the circulation volume of the electrodeposition waste liquid being 60-90m < 3 >/h.cell; 5-10% by volume of the discharged electrodeposition waste liquid is subjected to filter pressing, anode mud is discharged, the anode mud subjected to filter pressing is returned to zinc hydrometallurgy leaching, and the electrodeposition waste liquid subjected to filter pressing and the remaining 90-95% by volume of the electrodeposition waste liquid are returned to a system for cyclic utilization. In the zinc electrodeposition process, low-concentration electrodeposition and low zinc drop are combined wi
