从低品位、高铁含量铀矿石中提取“111”产品

Extracted from Low Grade and High Iron Content in Uranium Deposit Genesis "111" Products

对以低品位、高铁含量铀矿石中,用常规酸浸工艺提取铀效率低、成本高,且无法生产合格产品的矿石。经多次试验研究,成功解决了该项技术难题,生产出合格的"111"产品。为我国开发利用低品位的中、小型铀矿床,进行残矿回收,提供了技术保障和成功经验。

In this paper, with a low grade, high iron content uranium ore genesis, the low efficiency of uranium extraction by conventional acid leaching process, the cost is high, and can＇t production of qualified products of the ore. Through many times test research, results, solved the technical problems to produce qualified products ＂ 111＂. For our country the devel- opment and utilization of low grade of medium and small uranium deposit, remnant ore recovery, has provided the technical support and successful experience.
