Аннотация:The total concentrate of heavy lanthanides, zirconium, scandium, as well as emanating uranium andthorium can be recovered from the eudialyte ore concentrate breakdown solutions with help of 5-(diphenylphosphoryl)hexan-3-one within one technological extraction stage. The method makes it possible to separate the componentsof rare metal raw materials of various origins and generate concentrates suitable for further processing.The proposed new reagent of a series of phosphoryl ketones can be successfully used in the extraction processingof mineral and technogenic raw materials, enabling extraction and concentration of rare earth metals, as well as toseparate them from related impurities, in particular, from radioactive uranium, thorium and their decay products
