摘要
介绍了某难浸金精矿预处理工艺试验研究。研究结果表明 :不经预处理 ,该金精矿的氰化浸出率仅为 56 % ;经预处理后 ,氰化金浸出率可达 93%。该预处理工艺具有对环境污染小 ,投资少 。
The gold concentrate in a gold mine is refractory,of which the cyanide leaching rate is only 56%.Subject it to pretreatment,the cyanide leaching rate reaches 93%.Such pretreatment technology is characterized by less environmental pollution and capital cost and easy operation.
