Heap Leaching Studies on Uranium Ore. Phase VI: Field-Scale Heap Leaching Test Program

摘要

There is considerable interest in developing leaching techniques for low-grade uranium ores. For this study, a 2,500-ton low-grade uranium ore heap was tested to determine suitability of the heap leach extraction technique as a means of recovering uranium values. The results were compared with column leaches of the same ore. Flow rates were similar, and 96 pct of the uranium was leached in each system.
