铀矿石成分对铀的细菌浸出影响研究
Influence of Uranium Ores Constituent on Bacteria Leaching
【摘要】 对几种含不同成分的铀矿石进行了铀的氧化亚铁硫杆菌柱浸实验和耐性实验研究.柱浸实验结果表明,与硫酸浸出相比,细菌浸出可降低酸耗5%~20%.耐性实验结果表明,氧化亚铁硫杆菌经过驯化培养,能在铀质量浓度近2.0 g/L的环境中生存并可氧化Fe2+,耐F-可从驯化培养前质量浓度0.28 g/L提高到0.83 g/L.
【Abstract】 Bacteria column leaching and the domesticed incubation of bacteria test of ores from different uranium mines have been discussed in the paper.The results show that the(5%)~10% acid comsuption was reduced by bacteria leaching,that the uranium-tolerance of bacteria had been raised to 2.0 g/L,and that its fluoride-tolerance had been raised from 0.28 g/L to 0.83 g/L.
