| Abstract: | Acid-leaching method was used to recover zinc resource in the cathode substance of waste alkaline dry battery. Based on the experiment, factors influencing the leaching process as reaction time, reaction temperature, concentration of sulphuric acid as well as factors influencing the crystallizing process were optimised. With a series of process, the product of feed-grade zinc sulfate was obtained. |
