【摘要】 为了确定常温常压氨浸工艺的最佳浸出条件,在试验室采用搅拌浸出的方法,研究了云南东川汤丹难处理氧化铜矿常温常压氨浸的影响因素。其常温常压氨浸适宜的浸出条件是:氨浓度1~2 mol/L,矿石粒度-0.074 mm占80%~85%,液固比2∶1,浸出时间2 h。这一结论在生产实践中得到了验证。更多还原

【Abstract】 The effects of refractory copper oxide ore which comes from Tangdan of Yunnan Province were studied using agitation leach method in laboratory in order to find out the optimum leaching conditions under normal temperature and pressure.The optimum conditions obtained are as follows: ammonia concentration 1～2 mol/L,granularity(-0.074 mm) about 80%～85%,solid to liquid ratio 2∶1,and leching time 2 h,which were verified by industry application.更多还原
