| 摘 要： | 为了确定氨浸工艺的最佳浸出条件,在试验室采用搅拌浸出的方法,研究了云南兰坪难处理氧化锌矿氨浸的影响因素。其氨浸适宜的浸出条件是:氨浓度3 mol/L,碳酸氢铵浓度1.5 mol/L,磨矿细度-0.074 mm占85%,液固比4∶1,浸出时间2 h。在此条件下,获得了锌浸出率72.4%的较好指标。

| Abstract: | In order to determine the best leaching conditions of ammonia leaching process,through the method of laboratory stirring and leaching,the effecting elements of ammonia leaching refractory zinc oxide ores of Lanping,Yunnan Province are studied.The optimum conditions are obtained as follows:ammonia concentration 3mol/L,ammonium bicarbonate 1.5mol/L,granularity(-0.074mm) about 85%,liquid to solid ratio 4:1,and leaching time 2 h.Zinc leaching rate of 72.4% is obtained under the condition. |
