| Abstract: | The manufacturing technology of high purity and ultra fine zinc oxide powder,leaching out from zinc oxide mineral by the sulfuric acid,purifying of leaching liquor,synthesizing basic zinc carbonate,cleansing,drying and calcining was studied.Many condition tests were used to determine the optimum technology process.The zinc oxide powder obtained was tested by chemical composition analysis and construction analysis.The results show that the size of zinc oxide powder,the purity and the specific surface area were all better than the required standard. |
