石英-长石的浮选分离工艺研究

Research on Flotation Separation Process of Quartz-Feldspar

介绍了国内外石英-长石浮选分离的工艺现状,并对各种浮选方法的机理进行了具体分析。结果表明,浮选工艺研究由氢氟酸法到无氟有酸法,虽然实现了氟离子危害环境这一技术突破,但是由于酸对日常生产带来了很大的不便,如对设备的腐蚀等,因此,无氟无酸法更具发展前途。虽然无氟无酸法已取得了实验和理论上的成绩,但是对于投入实际生产还需进一步的研究和改善。

Introduces the status of the quartz-feldspar flotation separation process at home and abroad,and analyzes the mechanism of various flotation processes.The results show： the flotation process changes from ＂hydrofluoric acid＂ to ＂Non-Fluoride with acid＂ and achieves a breakthrough in solving the harm of Fluoride to environment,but acid is very inconvenient to daily production,such as corrosion of equipment,so＂Non-Fluoride and Non-acid＂ is more promising.Non-Fluoride and Non-acid has achieved experimental and theoretical results,but the actual production needs further study and improvement.
