| 摘 要： | 银洞坡金矿选一厂氰化浸出过程中存在着金浸出率低、泡沫外溢造成的金的流失和氰化尾渣含泥高严重影响氰化尾渣综合回收等主要问题。针对这些难题,提出并研究了磨矿与药剂组合的新工艺,使浮选金精矿品位由39 43g/t提高到53 19g/t,金浮选-氰化浸出总回收率由80 92%提高到90 54%;解决了所存在的三大难题。

| Abstract: | In the process of cyanide leaching at concentrator No1 in Yindongpo Gold Mine,there are some difficult problems including low gold leaching rate,froth overflow which causes gold loss and high slime content of cyanide residue which affects seriously the comprehensive recovery of useful metals in the residue.With a new proposed process of combining grinding fineness with reagent rate,these problems have been solved.The results show that the gold concentrate grade is increased from 39.43% to 53.19% and overall recovery of gold flotation-cyanide leaching from 80.92% to 90.54%. |
