某铀矿石硫酸浸出液中含有铀和铜，研究了从中综合回收铀和铜。试验结果表明：采用201×7树脂吸附铀，用酸性氯化钠溶液淋洗负载树脂，然后用氢氧化钠溶液从淋洗液中沉淀铀，铀回收率为98．4％；对铀的吸附尾液，采用循环铁粉置换法回收铜，铜回收率为90％。采用该方法可实现铀、铜的综合回收。
某鈾礦石硫痠浸齣液中含有鈾和銅，研究瞭從中綜閤迴收鈾和銅。試驗結果錶明：採用201×7樹脂吸附鈾，用痠性氯化鈉溶液淋洗負載樹脂，然後用氫氧化鈉溶液從淋洗液中沉澱鈾，鈾迴收率為98．4％；對鈾的吸附尾液，採用循環鐵粉置換法迴收銅，銅迴收率為90％。採用該方法可實現鈾、銅的綜閤迴收。

Recovery of uranium and copper from sulfuric acid leaching solution of a uranium ore has been studied .The results showed that uranium recovery was 98 .4% by adsorption uranium using 201 × 7 resin from the leaching solution ,and desorption uranium using acidic sodium chloride solution from loaded resin ,then precipitating uranium from the stripping liquid .The copper in the adsorption tail liquid was be replaced using iron powder ,recovery of copper was 90% .Comprehensive recovery of uranium and copper can be realized by the method .
