| 摘 要： | 近年来,生物技术在我国低品位砂岩型铀矿及老采区残留难浸铀矿的开发研究已开始起步。凭借生物浸铀具有的氧化性强、浸出液铀浓度及浸出率高等特点而成为开采该类铀矿的重要手段。文章以新疆某砂岩型难浸铀矿石浸泡浸出试验为例,系统开展了不同酸度条件下酸法浸出及不同Fe3+浓度条件下细菌浸铀试验。试验结果表明,生物浸铀在浸出液平均铀浓度、铀浸出率及浸出量等方面均高于酸法试验结果。

| Abstract: | In recent years, biotechnology in low grade sandstone type uranium deposits in China, and the development of old mining area remain refractory uranium ore research has begun to start. With the biological leaching uranium has strong oxidation, extract uranium concentration and high leaching rate and become an important means of this kind of uranium mining. The paper, taking a sandstone-type xinjiang immerse refractory uranium ore leaching test, for example, the system was carried out by acid leaching under the conditions of different acidity and Fe3＋ concentration under the condition of different bacteria leaching of uranium. The test results show that the biological leaching of uranium in leaching liquid average concentration of uranium, uranium leaching rate and amount of leaching test results are higher than acid method. |
