摘要
为给贵州某金矿综合利用其尾矿资源提供初步的技术基础,进行了试验研究,试验采用浮选的方法先将金富集在金精矿中,然后对这种金精矿采用焙烧-氰化浸出的方法进行处理。试验取得了较好的效果:金精矿品位达到43.4g/t,回收率达到90.56%,尾矿品位为0.21 g/t;焙烧后金精矿的浸出率可达80.94%。因此,在该金矿进行尾矿的综合利用是完全可行的。
In order to offer the preliminary technical base for the comprehensive utilization of the tailings from a gold mine in Guizhou Province, an experiment was carried out, in which the gold contained in the tailings was concentrated into the golden concentrate firstly by flotation, then golden concentrate was pro- cessed by roasting - cyaniding process. This experiment reached better results： the grade of gold concentrate reached 43.4 g/t, the recovery rate of gold reached 90.56% , the gold grade of the tailings was 0.21 g/t, the cyanidation- leaching rate of gold for the roasted gold concentrate was 80.94%. Therefore, it is feasible to carry on the comprehensive utilization of the tailings in this gold mine.
