摘要
根据中国某地浸采铀矿山铀矿石浸出液的成分特点,采用离子交换吸附工艺对浸出液中的铀进行回收试验研究。通过对多种条件试验,对离子交换树脂的选择、吸附、淋洗工艺参数等进行研究,结果表明201×7强碱性阴离子交换树脂和TSF-2阴离子交换树脂吸附和淋洗效果比较理想,确认采用固定床离子交换吸附工艺比较合适。六种淋洗剂的淋洗对比试验结果表明NH4NO3+HNO3适合作为本工艺的淋洗剂。
The absorption of uranium by ion-exchange resin is studied based on the characters of pregnant solution for a new uranium in-situ leaching mine. The resin types,the absorption parameters and the eluting parameters are chosen in the experiments. The results showd that the 201×7 strong alkaline anion exchange resin and TSF-2 anion exchange resin had good absorption and eluting effects. The fixed bed anion exchange absorption is a suitable technology and NH4NO3＋HNO3 mixed solution is an appropriate eluting reagent for this technology.
