摘要
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 railings 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 railings and ＂re-grinding and re-flotation＂, the flotation process obtained a gold concentrate grade of 25.23 g/t and a gold recovery rate of 55.08 % which were better technical indicators of beneficiation ; trial production achieved satisfactory economic benefits.
