氟碳铈矿是最重要的稀土矿物。其矿石的矿物组成复杂,含有比重和浮游性能相同的钙盐,钡盐和独居石矿物。是一种难选的稀土矿。本文根据近四十年分选氟碳铈矿捕收剂的科研和实践,将它分成四类:烷基羧酸类,羟肟酸类。芳烃膦酸类和芳烃羧酸类。较详细地讨论了各类捕收剂的捕收性能和应用价值,还简要地介绍了新近发展的组合用药。
Bastnaesite is the most important rare earth mineral. The mineral composition of the ore is complex and contains calcium, barium and monazite minerals with the same specific gravity and pelagic properties. Is an intractable rare earth mine. Based on the research and practice of sorting bastnaesite collectors for nearly forty years, this paper divides them into four categories: alkyl carboxylic acids and hydroxamic acids. Aromatic phosphonic acids and aromatic carboxylic acids. Discussed in more detail the collector performance and application value of various collectors, also briefly introduced the newly developed combination of drugs.
