摘要
FIELD: complex processing of phosphate raw materials. SUBSTANCE: origin solution comprises CaO, SrO, Al2O3, TiO2, Fe2O3; their limit concentrations being 2.7 g/l, 0.1 g/l, 2.4 g/l, 1.43 g/l, 1.41 g/l. Acidity of said solution is 0.4-4.0 N. Origin solution is treated by organophosphorous collecting agent having temperature not more 100 C; molar ratio of said agent and rare-earth elements is 3-6:1 respectively. Then thus treated solution is mixed and blown by air. Foam product being obtained is removed. Dialkylphosphoric acid having carbon chain with 7-14 carbon atoms is used as mentioned above collecting agent. EFFECT: improved efficiency. 3 cl, 1 tbl
