摘　　要：介绍了稀土冶炼工艺中氟的影响,并提出了一种清洁生产的新工艺。该工艺采用铝盐作络合剂,在浸出液中滴加铝盐溶液,氟与铝发生络合,达到氟与稀土分离的目的,从而排除了氟在稀土分离提取时的影响,提高了稀土回收率,是符合清洁生产要求的新工艺。The influence of fluorine on rare earth smelting was introduced,and a new clear producing process was put forward.In the process,aluminum salt was used as chelating agent.Through dripping aluminum salt solution in leaching solution,complexation of fluorine and aluminum was realized to separate the rare earth and fluorine to exclude the influence of fluorine on smelting process.The recovery of rare earth was improved,which can satisfy the requirements of clean production technology.

关 键 词：稀土 氟 清洁生产
