摘要
以从某铀矿矿石中分离出的一株铁氧化细菌(05B)为材料,研究了温度、初始pH值、接种量和初始总铁量对其生长的影响及其在铀矿浸出中的应用效果。研究表明:该菌株最适生长温度为40-45℃,最适接种pH值为1.5-1.7,初始接种量为10%-20%,初始接种总铁量以不超过5 g/L为宜。该菌用于低品位铀矿石浸出可取得较好的效果。
05B is a strain of iron-oxidizing bacterium which separated from a uranium ore. The effect of temperature, initial pH, inoculation amount and initial total iron concentration on the strain's growth and activities in bioleaching of uranium ores are studied. The results show that the optimum growth temperature is 40-45 ℃, the optimum inoculation pH value being 1.5-1.7, the optimum initial inoculation amount being 10%-20%, and the initial total iron concentration being not more than 5 g/L. 0513 is fit for leaching of low grade uranium ores.
