高泥尾砂浮选萤石实验研究

Experimental Research on Reprocessing Fluorite from High Mud Tailings

摘要: 为提高某铜锡萤石矿资源利用率，对其浮铜—除硫—磁铁—选锡尾砂中的萤石资源进行再选。实验采用碳酸钠为pH值调整剂、水玻璃与酸化水玻璃为抑制剂、BK410A为捕收剂，经1粗5精2扫浮选闭路实验流程，最终得到萤石精矿中 CaF₂品位90.51%、回收率66.13%。

Abstract: In order to improve the utilization rate of a copper-tin mine, The fluorite resources in floating copper-sulfur-removal-magnet-tin tailings were reselected.Sodium carbonate was used as pH agent, water glass and acidic water glass as inhibitors, BK410A as collector.a roughing test, two scavenging, five cleaning of flotation test process. Finally, the fluorite concentrate was obtained and the CaF₂ grade and recovery was 90.51% and 66.13%.
