黑捕收剂在硫化铜矿中的浮选实验研究

Experimental Study on the Flotation of Black Collector in Sulfide Copper Mine

硫化矿是较为重要的矿产资源,也是贵金属的主要来源,浮选是一种常用的矿石选矿方法,是目前硫化矿综合回收的首选方法。此次研究针对黑药捕收剂的特性,将其运用于硫化铜矿的浮选实验,通过对硫化铜矿和毒矿的性质进行分析,选择不同的磨矿细度和pH值调整来对硫化铜矿和毒砂进行实验最后在合适的指标下,对两种矿物进行闭路实验。实验结果表明,丁铵黑药与硫化铜矿的组合,可以获得金品位24.97g/t,其金回收率为87.92%。丁铵黑药对硫化铜矿的回收率高于毒矿3.65个百分点。研究表明,黑药捕收剂对硫化铜矿的浮选效果较高,能够给矿物加工行业提供一定的参考。

Sulfide ore is an important mineral resource and a major source of precious metals.Flotation is a commonly used ore dressing method and is currently the preferred method for comprehensive recovery of sulfide ore.This study focuses on the characteristics of black powder collectors and applies them to flotation experiments of sulfide copper ore.By analyzing the properties of sulfide copper ore and toxic ore,different grinding fineness and pH value adjustments are selected to conduct experiments on sulfide copper ore and toxic sand.Finally,under appropriate indicators,closed circuit experiments are conducted on the two minerals.The experimental results show that the combination of butylammonium black powder and copper sulfide can obtain a gold grade of 24.97g/t,with a gold recovery rate of 87.92%.The recovery rate of butylammonium black powder on copper sulfide ore is 3.65 percentage points higher than that of toxic ore.Research has shown that the flotation effect of black powder collectors on copper sulfide is relatively high,which can provide a certain reference for the mineral processing industry.
