摘要
应用软硬－酸碱理论、基团电负性理论、共轭体系作用及螯合效应作为判据，得出含有羧基和羟肟酸基活性基团的捕收剂是浮选氟碳铈矿的较佳捕收剂．
Bastnasite is the most important industrial rare earth mineral and it mainly associates with minerals of calcite and barite. The theories of hardsoft acid-base and electronegtivity of group, the effect of delocating bond systems, and the effect of chelation are utilized to judge the technological merits of several flotation agent. It is concluded that the flotation agents containing carboxyl and hydroxyl oxime groups are better suited for flotating bastnasite.
