蒙古苏木那林桃勒盖金矿矿石为典型的含金氧化矿，矿石矿物以石英为主，金属矿物含量少，金主要以自然金及银金矿形式存在，赋存状态以裂隙金和粒间金为主，含少量包裹金。根据该矿的矿石性质，采用重选-氰化联合选冶工艺可取得较好的选矿效果。原矿经尼尔森选矿机，可获得含金618.44×10-6的金精矿，金回收率为71.12%，重选尾矿全泥氰化，金浸出率为94.66%，尾矿含金可降至0.17×10-6，金总回收率达98.46%。

The gold ore is a typical gold bearing oxidized ore in Lintaolegai,Sumuna,Mongolia,mainly composed of quartz and containing little other metallic mineral,whose existing form is native gold and silver,as well as, dominated by crevice-gold and inter-granular gold with a small proportion of included gold.According to the ore properties,a technology of combining gravity separation with cyanide selection was adopt that lead to a good flotation result.Disposing raw ore by Nielsen separater,gold concentrate ore which containing 618.44 g/t gold were gained,with gold recovery of 71.12%,gold leaching rate of 94.66%,and the gold in tailing gold production was reduecd to 0.17 g/t.The total gold recovery rate was increasing to 98.46% along with the process of gravity separation whole mud-cyanidation for tailings.
