| Abstract: | Active zinc oxide was preparated from zinc ore by a series of steps such as lixiviating, purifying,hydroly-zing,drying and calcining,and ammonium chloride as a lixiviating agent instead of sulphric acid in existence. Optimum process conditions and factors affecting the results were obtainedtemperature of lixiviating is 60℃.time is 2 h, the lixiviating ratio of zinc is 91 %. Temperature of hydrolyzing is 50℃ .time is 2 h.zinc content of the solution is 15 g/L with more than 96% hydrolyzing ratio. |
