介绍了鹿儿坝含砷难浸金矿石细菌氧化柱浸试验研究结果。对 5 mm粒度的试验样品 ,采用T1 1 0 1 细菌氧化 6 8d,砷的氧化率达到 5 9.32 % ,金的浸出率为 72 .99% ,比直接氰化柱浸金浸出率提高 6 0 %以上 ,有效地解决了试验矿石的难浸问题。
The results of bacterial oxidation column leaching test of arsenic-refractory gold ore in Lu’erba were introduced. The oxidative rate of arsenic reached 5 9.32% and the leaching rate of gold was 72.99%, which was 60% higher than that of direct cyanide column leaching with 5% Above, effectively solve the difficult problem of test ore leaching.
