介绍钨浮选新药剂OS-2及在柿竹园有色金属有限责任公司野鸡尾选矿厂的应用情况。实验室试验和工业试验结果表明,采用OS-2获得钨粗精矿品位和回收率均高于现场的药剂,实验室试验以该药剂浮选含WO3 0.36%的原矿,获得粗精矿含W03 13.29%、回收率80.49%。对含W030.38%的原矿进行的工业试验,获得粗精矿含W03 12.12%、回收率77.76%的选别指标。该药剂对钨矿物的可浮性好、选择性强,便于现场操作和管理,经济、技术指标良好。
This paper introduces the new application of tungsten flotation OS-2 and its application in the wild chicken tailings concentrator of Shizhuyuan Nonferrous Metal Co., Ltd. The results of laboratory tests and industrial tests show that OS-2 was used to obtain the grade and recoveries of tungsten crude concentrate higher than those in the field. In laboratory experiments, the ore was flotated with 0.36% WO3 to obtain crude concentrate containing W03 13.29%, the recovery rate of 80.49%. Industrial tests on raw ore containing W030.38% obtained a sorting index of crude concentrate containing W03 of 12.12% and a recovery rate of 77.76%. The agent of flotation of tungsten minerals good, selective, easy to site operation and management, economic, technical indicators are good.
