摘　　要：某难处理铀矿石采用常规酸法搅拌工艺浸出时，酸耗高，浸出液后处理难度大。采用加压酸浸工艺，酸耗可降低约30％，浸出液余酸质量浓度降至2～4 g／L ，无需再处理即可满足下一处理工序的要求。By conventional agitation leaching to deal with a refractory uranium ore ,the acid consumption is high ,and the leaching solution is treated difficulty .By pressure acid leaching ,the acid consumption can decrease by 30% and the concentration range of residual acid in the leaching solution is of 2-4 g/L and suitable for the next treatment .
