摘要
针对翁源铀矿石角围矿区高酸耗、难处理矿石,进行细菌柱浸试验,并与加氧化剂(氯酸钠)酸法柱浸进行对比。结果表明:采用细菌柱浸方法可大幅度降低酸耗。与加氧化剂(氯酸钠)酸法柱浸相比,细菌柱浸酸耗降低64.9%,铀浸出率提高2.6%,因此有望将细菌堆浸法应用于处理石角围矿石的工业生产中。
Bacteria column leaching and acid plus oxidant（sodium chlorate）column leaching experiments of a high acid consumption uranium ore were carried out.The results of the experiments were compared.It is showed that,compared with acid plus oxidant column leaching,the acid consumption of bacteria column leaching was reduced by 64.9%,and the leaching rate of uranium was increased by 2.6%.So,the bacteria heap leaching method is expected to be applied to industrial production of treating this high acid consumption uranium ore.
