| 摘 要： | 石英常与长石类硅酸盐矿物共生，由于两者相似的物化性质使其分离提纯难度较大。浮选法是石英与长石分离最有效的方法，详细综述了氢氟酸法、无氟有酸法和无氟无酸法等石英与长石分离的主要浮选方法，指出无氟无酸法和预处理强化浮选是未来技术发展的重点方向。在药剂研究方面，目前主要集中在阴阳离子组合捕收剂、抑制剂、金属离子活化等的设计与开发，但机理研究较少。

| Abstract: | Quartz is often symbiotic with feldspar silicate minerals, which is difficult to separate and purify because of their similar physical and chemical properties. Flotation is the most effective method for the separation of quartz and feldspar. The main flotation methods for the separation of quartz and feldspar, such as hydrofluoric acid method, fluoride-free acid method and fluoride-free acid method, are reviewed in detail. It is pointed out that fluoride-free acid method and pretreatment enhanced flotation will be the key direction of technological development in the future. In pharmaceutical research, the current focus is on the design and development of combined cationic and anion collectors, inhibitors, metal ion activation and so on, but the mechanism research is less. |
