Description
Phosphorites present the major mineral source for the mineral fertilizers production. But the phosphorites of sedimentary origin are radioactive due to certain concentration of uranium, thorium, radium, lead, polonium. Large reserves of phosphorites and their large quantities involved into fertilizers processing make them consider a potential source of uranium, even at the initial concentration 0.00500.01%. Recovery of uranium as by-product while processing phosphorites also facilitates manufacture of environment safe fertilizers. The present report describes the results attained in extraction of decontaminated phosphoric acid with a novel efficient extractant of polyalkyl phosphazenes-PN-1200
