Abstract
Physico-chemical and mathematical models of distribution of lanthanides(III ) between water-salt solutions, containing salting-out agents, complexones (ethylendiaminetetraacetic (EDTA) and diethylen-thriaminepentaacetic acids (DTPA)) and neutral organophosphorus compounds (NOPC) are introduced. Examp les of separation of rare earth elements concentrates with application of N OPC, complexones and ammonium nitrate is considered.
