某低品位高硫高碳难处理金矿无氰堆浸工艺工业试验研究

Industrial experimental research on heap leaching of low-grade refractory gold ore bearing high sulfide and carbon without cyanide

摘要: 贵州泥堡金矿为低品位高硫高碳高粘土含砷的微细粒难处理金矿, 采用新型环保型浸金药剂进行浸金工业试验, 取得了与氰化浸金工艺相当的效果.此法的成功应用和推广对今后金矿的无氰堆浸生产有一定的指导作用.

Abstract: The Micro-fine grained gold ore is low-grade refractory gold ore bearing high sulfide, carbon, clay and arsenic in Nibao, Guizhou. A new environmentally friendly reagent to gold leaching is employed, and the effect of which is equal to those industrial experiments with cyanide. The application and promotion of this technology provides some guidance to the cyanide-free gold heap leaching.
