摘　　要：针对某含钼铀矿石碳酸盐含量高的特点,在工艺矿物学研究的基础上,开展碱法浸出工艺条件试验。研究结果表明:采用拌碱熟化柱浸工艺,能较好地实现矿石中铀、钼的提取;钼浸出率可达90%以上,铀浸出率为85%左右;浸出周期较常规碱法缩短了60d。Based on the results of process mineralogical research of a carbonate type uranium-molybde- num ore, leaching behaviors of the uranium-molybdenum ore were studied by alkali agitation leaching, conventional alkali column leaching and alkali curing column leaching processes. The results showed that using the alkali curing column leaching process, the leaching rate of molybdenum increased to more than 90%, and the leaching rate of uranium was about 85%. Compared with the conventional alkali column leaching process, the leaching time of the alkali curing column leaching process decreased by 60 days.
