摘　　要：利用某地难选冶金矿 ,选用工业废弃物作为固化剂 ,进行固硫固砷预处理。不仅使硫化物中包裹金基本上能解离并被氰化物浸出 ,而且还克服了传统氧化焙烧工艺中S、As被氧化后随烟气进入空气中污染环境的弊端。A fixing agent originated from indurstrial waste was selected for fixing sulfur and arsenic in pretreating technology of a refractory gold ore After using the pretreating technology,the gold covered by sulfide minerals could be dissociated from sulfide and then leached by cyanide,and the malpractice of environmental pollution by smoke contained S and As oxides in traditional oxidizing roasting process of the gold ore could be overcome

关 键 词：难选冶金矿 预处理 金矿石
