Working out of resource-saving technology of enrichment of phosphate-raremetall ores

Possibility of complex use of phosphate-raremetall ores of the Tatar deposit is proved. Results of researches of crystal-chemical features of the minerals which are a part of rejects of electric separation of ore-dressing plant of the Tatar deposit ores on which basis perspective reagents are chosen are stated. Law of action of the chosen reagents on minerals of electric separation rejects is established. On the reagents which have given the best indicators of flotation on monofractions, researches on rejects of factory with use of the multilevel factorial plan 33⁄9 are conducted. It is received an apatite concentrate with the maintenance of Р2О5 39,9 % at extraction of 98,5 %.
