| 摘 要： | 以NH3—NH4C1体系浸出某高碱性氧化锌矿,考察了氨浓度、液固比、时间和温度等因素对锌浸出率的影响,并分析了相应的浸出过程,得到的最佳实验条件为:NH3:NH4Cl摩尔浓度比为1∶1、氨浓度5 mol/L、液固比为3∶1、浸出时间为2 h、浸出温度40℃,此时锌浸出率为89.3%。

| Abstract: | The leaching of a high alkaline zinc oxide ore was studied in ammonia-ammonium chloride solution.The influence of technical parameters including ammonia concentration,the ratio of liquid to solid,reaction time and temperature on leaching rate was studied and the relevant leaching process was analyzed.The optimum condition was found to be： the molar concentration ratio of ammonia to ammonium chloride is 1：1,the ammonia concentration is 5mol/L,the ratio of liquid to solid is 3：1,the leaching time is 2h and the leaching temperature is 40℃.The leaching ratio of zinc is 89.3% under that condition. |
