Micro-fine particle lepidolite collecting agent and preparation method and application thereof

The invention discloses a micro-fine particle lepidolite collecting agent which comprises the following four components: 20-40% of a mixed cation component, 30-50% of a mixed anion component, 10-30% of a stabilizer and auxiliary flotation component and 10-30% of an emulsifier component. And the method is particularly suitable for grinded minerals and slime of fine lepidolite with complex dissemination granularity or very low grinding fineness, and has the characteristics of high enrichment ratio and high recovery rate of the fine lepidolite concentrate. 本发明公开了一种微细粒锂云母捕收剂，包含以下四个组分的物质：混合阳离子组分20-40％、混合阴离子组分30-50％、稳定剂及辅助浮选组分10-30％、乳化剂组分10-30％。尤其适用于于嵌布粒度复杂或是磨矿细度很低的细粒锂云母磨后矿物与矿泥，具有微细粒级锂云母精矿富集比高、回收率高的特点。
