This paper explores a novel method to recycle the waste zinc-manganese battery with high added-value product by evaporation-separation, sulfurization and inert gas condensation. The heating temperature, condensation temperature, nitrogen gas pressure and condensation distance are identified as the main influencing factors of the morphology of ZnS nanoparticles prepared. Pretty pure and ultrafine ZnS particles can be prepared when the heating temperature is 873K, the condensation temperature is 723K and the nitrogen gas pressure is 1000Pa-1500Pa at the condensation distance of 30cm. The size of these ZnS particles is between 10 nm and 100 nm, and the average size is about 40 nm. Based on the scientific graphing and statistical analysis, the size of ZnS particles follows the log-normal distribution. This paper does not only provide the theoretical fundamental for preparing ultrafine ZnS particles, but also provides a simple and efficient method to recycle the high added-value ZnS products from waste zinc-manganese batteries.
