| 摘 要： | 本文阐述了从含钨泥质铀矿石中回收铀及铀钨分离的试验研究。对碳酸盐含量高的该种矿石,采用加压碱浸、离子交换分离铀、钨和吸附后溶液全部返回浸出回路的流程,可获得部颁一级品重铀酸铵产品,并使浸出剂碳酸钠的用量大幅度降低。

| Abstract: | This paper describes the method and experimental results of extraction of uranium from the carbonate-type argillaceous uranium ore containing tungsten and their separation. This kind of uranium ore with high content of carbonates is treated using carbonate leaching under pressure, ionexchange separation of uranium from tungsten and recycle of the adsorbed solution
to the leaching circuit. According to the mentioned Process, the ammonium diuranate of class I can be obtained and the consumption of sodium carbonate
reagent can be reduced considerably. |
