中文摘要: 采用200 g/L的硫酸对生物浸出后期的铀矿堆进行熟化试验。结果表明，相同时间内熟化后的浸出率是相邻时间段生物浸出的3倍，表明生物浸出尾期采用高酸熟化对提高浸出率、缩短浸出周期是可行的。
Abstract:The bio-leaching tailing heap was aged with 200 g/L concentrated sulfuric acid to recover uranium. The results show that the uranium leaching rate of aged ore is triple compared with that of within adjacent period of time. It is proved that concentrated sulfuric acid aging is effective to improve uranium leaching rate and shorten leaching period.
