某硬岩铀矿石细菌柱浸试验研究

Experimental Research on Bacteria Column Leaching of a Hard Uranium Ore

以某硬岩铀矿石为研究对象,对其进行了细菌柱浸与酸法柱浸浸铀对比试验研究。试验成果表明,细菌柱浸比酸法柱浸能降低耗酸0.5个百分点,提高铀浸出率8个百分点,缩短浸铀周期10 d以上,说明应用细菌对该矿山铀矿石的浸出具有一定的可行性。

Bacteria column leaching and acid column leaching experiments of a hard uranium ore were carried out. The results of the experiments were compared and studied. And it is showed that, compared with acid column leaching, the acid consumption of bacteria column leaching was reduced by 0.5% , meanwhile, the leaching rate of uranium was increased by 8% , the leaching period was shorten by 10 days at least. The experiments showed that the bacteria leaching of this uranium ore is feasibility.
