Zusammenfassung: | The invention provides a rapid judgment method for purifying cobalt-removed zinc powder in zinc hydrometallurgy, and relates to the technical field of zinc hydrometallurgy. The rapid judgment method for purifying the cobalt-removed zinc powder based on zinc hydrometallurgy comprises the following steps: taking to-be-screened zinc powder, and performing specific analysis and detection; screening according to a detection result, and selecting qualified zinc powder for a verification experiment; taking a certain amount of pre-purification liquid to a reactor, setting a rotating speed, and heating to a preset temperature; adding a certain amount of zinc powder and C4H2KO7Sb.1/2H2O, reacting for a period of time, and carrying out solid-liquid separation; and when Co in the filtrate is determined to be lower than 0.20 mg/L by adopting a nitroso R salt photometric method, the zinc powder is qualified. Whether various kinds of zinc powder can be used for the zinc hydrometallurgy purification process or not is judged |
