摘要
云南省某含砷难浸金精矿 ,常规氰化金浸出率仅为 2 6 .17% ,通过采用细菌氧化预处理后 ,金浸出率达到 98.2 5 % ,获得了非常理想的试验指标。
A certain arsenic bearing refractory gold concentrate of Yunnan Province were treated by conventional cyanide process,however,the gold leaching rate was only 26.17%.Through pretreatment by bacterial oxidation,the gold leaching rate reached 98.25%,getting quite satisfactory result.
