摘要
通过对难浸金精矿掺入一定比例骨架材料,解决了矿堆渗透性差难题,选用适宜菌种对金精矿进行堆浸细菌氧化—氰化浸出,金的浸出率由常规氰化62.88%提高到93.32%。该研究结果表明,采取适宜条件金精矿亦可用堆浸细菌氧化—氰化工艺处理。
By adding a certain proportion of framework materials into refractory gold concentrate,the problem of low penetrability was solved.Proper bacterial strain was chosen to carry out the bio-oxidation cyanidation process.As a result,the leaching rate of gold was raised from 62.8% to 93.32%.
