锂辉石浮选尾矿综合利用试验

Experiment on Comprehensive Utilization of Spodumene Flotation Tailings

为使矿山资源利用率最大化,有效的回收利用矿山现有废弃资源,通过对某锂辉石矿选矿厂浮选尾矿进行矿物分析,采用浮选—磁选—浮选的选矿工艺流程回收尾矿中的云母、石英、长石等有用组分。试验获得了产率为18.31%的云母精矿,产率为37.38%、钾钠合量为13.30%、1200℃煅烧白度为78.9%的长石精矿,产率为28.07%、SiO2品位为98.34%、F2O3含量为0.038%的石英精矿;有效回收了矿山废弃资源、降低了尾矿排放量,达到了矿产综合利用的目的。

In order to maximize the utilization rate of mine resources and effectively recycle the existing waste resources of the mine,through mineral analysis of flotation tailings of a spodumene ore concentrator,the beneficiation process of flotation-magnetic separation-flotation is adopted to recycle mica,quartz,feldspar and other useful components in the tailings.Mica concentrate with yield of 18.31%was obtained.The yield of 37.38%,the amount of potassium and sodium is 13.30%,and feldspar concentrate with whiteness of 78.9%is calcined at 1200℃.The yield of 28.07%,SiO2 grade of 98.34%,F2O3 content of 0.038%was obtained.Thus effectively recycling the waste resources of the mine,reducing the discharge amount of tailings and achieving the purpose of comprehensive utilization of minerals.
