中文摘要: 对某铀矿石进行了多桶串联细菌溶浸试验,分析了串联装置和充气时间对浸出率、酸耗的影响。结果表明,该矿石三桶串联、两桶串联和单桶的铀平均浸出率分别为82.33%、81.42%和83.62%,同一串联工艺中,越靠后的桶的铀浸出率越低,耗酸也越低;另外,充气可以明显加快离子交换速度,提高细菌活性。
Abstract:The bacterial leaching experiment was carried out for uranium ore under series connection conditions. The effects of series connection equipment and air inflation time on uranium leaching rate and acid consumption were analyzed. The results show that the average uranium leaching rates of three-barrels-series connection, two-barrels-series connection and single-barrel are 82.33%,81.42% and 83.62% respectively. The uranium leaching rate and acid consumption of the barrel rely on the latter are lower. Inflation can accelerate ion exchange speed and improve bacterial activity obviously.
