AbstractAbstract
[en] A shallow hole shrinkage mining stope leaching method was used to recover uranium in a uranium mine. The problems such as large blasting fragmentation and uneven distribution of drill lixiviant resulted in low leaching rate, long leaching cycle and low production efficiency during production. Aimed to problems and combined with the actual situation of the uranium mine, the shallow hole shrinkage mining method was improved, that is, according the results of geophysical logging, high grade ores and low grade ores were blasted and mined respectively, and the high grade ores were sent to the surface and treated by heap leaching process, and low grade ores were leached in stope. This improved method was called shrinkage mining method with respective blasting and mining. Compared with shallow hole shrinkage mining stope leaching method, the recovery rate of the improved method was increased by 17.2%, thereby maximizing the recovery of uranium resources. (authors)
