某高碳金矿石氰化尾渣中金品位高达3．09 g／t。为进一步回收利用该尾渣中的金矿物，对其进行了浮选试验研究。通过对该氰化尾渣进行预处理和“再磨再选”的浮选工艺流程，获到金精矿品位25．23 g／t、金回收率55．08％的较好选矿技术指标；试生产取得了较好的经济效益。
Gold grade in some carbonaceous gold cyanidation tailings is up to 3.09 g/t.To further recover gold minerals from the tailings,experimental study of flotation was carried out.By pre-processing the cyanidation tailings and “re-grinding and re-flotation”,the flotation process obtained a gold concentrate grade of 25.23 g/t and a gold re-covery rate of 55.08 %which were better technical indicators of beneficiation; trial production achieved satisfactory economic benefits.
