紫金山金矿含金固体废弃物的综合利用

Comprehensive Utilization of Goldbearing Solid Waste from Zijinshan Gold Mine

针对福建省紫金山金矿含金固体废弃物含金量低、含泥量高的特点,进行了深入的实验室试验研究,探讨了不磨矿直接洗矿、粗粒级堆浸、细粒级全泥氰化组合新工艺。试验结果说明该工艺适合此类矿石的再利用,对中国其他地区的大型特大型金矿固体废弃物的利用,也有重要的借鉴推广意义。

According to the characteristics of solid waste containing lowgrade gold and highcontent clay in Zijinshan Gold Mine,Fujian,a new technology composing of nogrinding,direct washing,coarse fraction be sent to leaching and fine fraction to all sliming cyanidation was proposed to treat the waste.The results indicated that the permeability of ore heap can be increased,the time for heap leaching can be reduced and leaching rate can be increased.
