An experimental research was preformed for the development of an effective process for zinc oxide waste(zinc ash) reuse. Zinc was selectively leached from zinc ash by 30 vol.% D_2EHPA in kerosine solution, and the leaching velocity was quite fast. Zinc leached was stripped by sulfuric acid solutions, and the amount of zinc stripped was linearly increased with the amount of sulfuric acid used. Zinc oxide fine particles were obtained by dropwise adding of sodium hydroxide solution to the resultant aqueous zinc solution at 85℃.
