摘　　要：该金矿为低品位氧化型金矿。通过活化含金矿物,使其成为浮游性较好的矿物形态,再经浮选富集,金精矿品位达到21.75g/t,回收率78.46%。浮选精矿产品直接氰化浸出,金浸出率达到97.62%;金选冶总回收率76.59%。采用浮选氰化浸出的选冶联合方案,可使同类型低品位金矿资源的综合开发利用成为可能。The ore is a low-grade oxidized gold ore.By means of activating the minerals containing gold to make them easier floated.After flotation concentration,a gold concentrate of 21.75g/t Au was obtained with a recovery of 78.46%.Under the condition of direct cyanide leaching of flotation concentrate,the leaching rate of gold achieved 97.62%,and the total gold recovery of flotation and cyanide leaching processes reached 76.59%.Thus,it is believed that by adopting the combined flowsheet of mineral processing and metallurgy,it is possible to realize comprehensive exploitation and utilization of similar kinds of low-grade gold mineral resources.
