萤石矿低温浮选高效捕收剂的研究与选矿应用

Research and Application on Low-temperature and High-efficient Flotation Collector for a Fluorite Ore

为解决萤石矿浮选捕收剂油酸在常温下水溶性及分散性差、能耗高的问题,本项目以内蒙古某萤石矿为试验研究样品,进行萤石矿低温浮选药剂的研发,研制的新药剂YS103能够在矿浆温度5-10℃条件实现对萤石矿的有效捕收及萤石与杂质矿物的有效分离。对新药剂YS103开展了浮选性能研究、小型试验及工业应用试验,用YS103替代现场使用的油酸,在无需加温的情况下均取得了良好的选矿指标。

In order to deal with the low solubility and dispersivity, high energy consumption of oleic acid at room temperature,a low-temperature flotation reagent of fluorite was studied.With an Inner Mongolia fluorite as the experimental sample, fluorite and impure minerals were separated effectively at 5-10℃ was realized by using new reagent YS103,which is the effective collecter of fluorite.The paper studied the flotation performance of YS103,and bench-scale tests and Industrial application test were carried out with YS 103,which insteads of oleic acid,we achieved good dressing index without elevating temperature.
