酸化－硫化沉淀工艺处理紫金山金矿堆浸贵液工业调试及评价

摘要

Debugging of treatment process of pregnant solutions from heap leaching in the second ore-dressing plant of Zijinshan Gold Mine by acidification-sulphidization method is carried out.The results showed that the technol-ogy can not only eliminate the adverse effects to low grade gold ore processing caused by cyanide soluble copper min-erals,but also can recover cyanide to recycling and recover copper concentrates which can be sold,reducing the opera-tion cost of gold production,improving the comprehensive benefits of the enterprise,having great promotion value in Zi-jinshan Gold Mine and other similar mines.%针对紫金山金矿二选厂堆浸贵液进行了酸化－硫化沉淀法处理工艺的工业调试，结果表明：该技术不仅可以消除氰化物可溶性的铜矿物对低品位金矿浸出造成的不良影响，而且可以回收氰化物使其循环利用，还可以回收可销售的铜精矿，降低了黄金生产的运行成本，提高了企业的综合效益，在紫金山金矿和其他相似资源的金矿生产企业具有极大的推广价值。
