难处理萤石矿常温浮选是选矿的难点之一。萤石常温(15℃)浮选药剂研究包括不同类型萤石矿浮选药剂应用现状、萤石浮选捕收剂的改性研发、萤石新型常温(15℃)捕收剂,萤石高效脉石抑制剂的研究。本文基于萤石矿与含钙脉石及硅酸盐脉石浮选分离困难、传统的油酸及其改性产物作为萤石浮选捕收剂的局限性等现状,为了实现萤石资源更好地开发与利用,总述了萤石矿的分类及其常规浮选药剂方案,重点分述了萤石新型常温(15℃)浮选捕收剂种类及捕收性能、油酸低温浮选药剂改性研究、萤石浮选调整剂及其作用机理,以及萤石常温浮选捕收剂应具备的适宜的极性基团,能够在萤石表面的吸附能力优于脉石,受温度影响较小,融点应较油酸低,抗硬水,能够在较低的温度保持其溶解度和分散能力等基本性能;最后指出了萤石选矿的难题和今后研究的方向。
Room temperature flotation of refractory fluorite ore is one of the difficult points in mineral processing. Fluorite at room temperature （ 15℃ ）flotation reagent research comprises the application status of flotation reagents in different types of fluorite ores, a collection agent modified research and development, fluorite new room temperature （ 15℃）collector fluorite flotation collectors, and efficient gangue inhibitor of fluorite. Based on the present situation of the difficulties of fluorite ore and gangue and calcium silicate gangue flotation separation, traditional oleic acid and its modified products have limitations as fluorite flotation collector. In order to achieve better development and utilization of fluorite resources, this paper executive summary of fluorite ore classification and conventional flotation reagent scheme, focusing on the flotation of fluorite new room temperature （15 ℃ ）capture agent types and catchability, oleic acid low-temperature flotation reagent change research, fluorite flotation adjustment agent and its mechanism of action, and suitable polar groups of fluorite flotation collectors at room temperature, in the fluorite surface adsorp- tion capacity is better than that of gangue,less affected by temperature, the melting point is low oleic acid, anti hard water, can maintain its solubility and basic properties of dispersion ability at low temperature, etc. Finally it is pointed out that the fluorite ore dressing of the problems and the research direction in the future.
