研究了从中国南部某铀矿床含铀废矿中堆浸回收铀的可行性。在废矿场建设了一个4500吨的工业堆。废矿样粉碎至-25 mm，矿石铀品位为0.0211%。生产146d后，渣铀浸出率为55.92%，渣中铀含量为0.0093%，酸耗为2.69%(以矿重计)。研究证明，用堆浸方法从含铀废矿中回收铀是可行的。
The feasibility of heap bioleaching recovery of uranium from the one Uranium Mine deposit uranium-bearing waste ore, located in south of China, were investigated. A 4500 ton industrial heap was constructed in the waste ore dump site. The waste ore sample was crushed to -25 mm, the ore uranium grade is 0.0211%. After 146 days of performance, the slag uranium leaching rate was 55.92% that calculated by its residue has been recovered, content of uranium in residue was 0.0093%, the acid consumption rate was 2.69% by ore weight. The study has proven that recovery uranium from uranium-bearing waste ore using heap bioleaching is feasible.
