Recovery Uranium from Uranium-Bearing Waste Ore Using Heap Bioleaching

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.
