摘要
介绍了草桃背分矿细菌堆浸工业试验结果 ,并对筑堆、喷淋布液系统的安装、生物氧化槽运行管理作了概述。通过 85 d淋浸试验 ,回收铀 685 9kg,液计浸出率 92 .95 % ,渣计浸出率 91 .88% ,酸耗 2 .1 % ,总液固体积质量比 2 .9m3/t。和常规堆浸比较 ,浸出周期缩短约 75 d,酸耗节省 0 .3 5 % ,铀浸出率提高 2 %。
This paper presents the result of commercial experiment on bacteria heap leaching of uranium ore from Caotaobei mining area in Ganzhou Uranium Mine and summarizes the heap situation,installation of spraying and sprinkling devices,and operation management of continuous oxidizing tank of biomembrane. The leaching rate is 92.95%and 91.88% respectively by liquid and residue measurement during 85 d bacteria leaching experiment. The acid consumption is 2.1% and the total liquid solid ratio is 2.9 m 3/t. Compared with conventional heap leaching, the time of bacteria heap leaching shorted about 75 d, the acid consumption reduced by 0.35% and the leaching rate improved by 2%. It is an optimize plan to reform the heap leaching technology for Caotaobei ore.
