摘要
对某铀矿堆浸尾渣进行了不同喷淋间隔的微生物柱浸试验,3个柱每次的喷淋量都为2%,喷淋制度采用喷淋6h间隔分别为18、42、66h。结果表明,经过300天的喷淋以及100天的放置后洗堆,铀浸出率分别达到87.83%、77.23%、80.60%,浸出溶液铀浓度大于50mg/L。
The low grade uranium heap leaching tailing was column bioleached with different spraying intervals.The spray amount of three columns is 2 % each time.The spraying is 6 h in duration with intervals of 18 h,42 h,and 66 h respectively.The results show that uranium leaching rate is 87.83%,77.23%,and 80.60% respectively after 300-day of spraying and 100-day of placement and washing.The uranium concentration in leaching solution is 50 mg/L above.
