RE-EXTRACTION METHOD OF RARE-EARTH METALS FROM ORGANIC SOLUTIONS AND OBTAINMENT OF CONCENTRATE FROM RARE-EARTH METALS Russian patent published in 2015 - IPC C01F17/00 C22B3/26 C22B59/00

Abstract RU 2538863 C2

FIELD: metallurgy.

SUBSTANCE: invention refers to liquid extraction processes, in particular to obtainment of rear-earth metals concentrates, in non-ferrous and ferrous metallurgy, during utilisation of chemical and metallurgical production waste and for purification of shaft, mine and industrial waste water. The method of rear-earth metals removal from diluted water acid solutions involves consecutive steps of liquid-phase extraction of rear-earth metals to organic phase and re-extraction of rear-earth metals from organic phase by settlement of rear-earth metals to solid phase in the form of slightly soluble salt of strong acid.

EFFECT: providing efficient removal of rear-earth metals without neutralising of acid containing in organic phase and use of cheap commercially available reagents.
