独居石的选矿一般是应用重选、磁选、静电选矿的联合流程。但在处理含独居石的泥矿时也有必要应用浮游选矿法。据美国专利[Climax.Molybdenum co,Patnted,Sept、1952.№ 2610738]用浮选法可使独居石及磷酸盐矿物与其它重矿物分离回收。浮选剂是应用胺系列的阳离子捕收剂并加以适量的淀粉质,在酸性介质中进行浮选独居 Monazite mineral processing is generally applied re-election, magnetic separation, electrostatic beneficiation of the joint process. However, the treatment of monazite containing mud is also necessary to apply the floatation beneficiation method. According to the U.S. patent [Climax.Molybdenum co, Patnted, Sept, 1952. No. 2610738], monazite and phosphate minerals can be separated and recovered from other heavy minerals by flotation. Flotation agent is the use of amine series of cationic collector and to the right amount of starch, flotation in acidic medium living alone
