摘要
以山南铀矿石为槽浸对象,通过实验研究了酸化预处理对细菌浸铀的影响。对比实验结果发现,采用稀硫酸酸化的方式可以加快氧化亚铁硫杆菌和氧化硫硫杆菌对铀矿石的适应速度,提高混合菌浸出U(Ⅳ)的效率,但酸化时间太长对总的浸铀效率不利。
Taking the ore from Shannan Uranium Mine for trench - leaching object, the influence of acidification pretreatment on bioleaching uranium has been researched by trench -leaching experiments. Comparing the experimental results, it is found that by adopting method of acidification pretreatment with dilute sulfuric acid, the adaptation of thiobacillus ferrooxidans and thiobacillus thiooxidans to the uranium ore can be accelerated, the efficiency of leaching uranium（IV） can be increased also, however, too long acidification time is not favorable for the total efficiency of leaching uranium.
