Specifications:
Preparation:
The extraction method takes the rare earth chloride solution obtained by processing monazite or mixed rare earth ore as raw material, extracts, groups, and uses the raffinate to lift the light rare earth, extracts the samarium and heavy rare earth into the organic phase, and then back-extracts the heavy rare earth to obtain The rare earth samarium-gadolinium enrichment, reduction, extraction of europium, and then precipitation, separation, drying and burning of oxalic acid to obtain europium oxide.
