Method for separation and purification of fluorescent grade yttrium oxide and europium oxide from waste phosphor powder

The invention relates to a method for separation and purification of fluorescent grade yttrium oxide and europium oxide from waste phosphor powder, comprising the steps of: first conducting impurity removal so as to obtain mischmetal containing Y2O3 and Eu2O3, then dissolving the mischmetal with an acid solution for preparing a rare earth feed liquid, and carrying out extraction with an extraction system after alkaline solvent saponification, thus obtaining the raffinate, washing liquid and strip liquor; adding an oxalic acid solution and conducting filtration, then subjecting the obtained filter residue to calcination, thus obtaining the fluorescent grade yttrium oxide, and yttrium-rich rare earth and europium oxide. The invention has the advantages that, reagents are of wide source, lowprice and easy availability, and the simple process of the method can greatly shorten the extraction process of naphthenic acid. In the invention, three deposition impurity-removal treatments before extraction can remove most impurities and leave only a small amount of aluminium and silicon, so that an emulsification phenomenon in the naphthenic acid extraction system cannot be caused, thus providing a good solution to the problem that naphthenic acid extraction is susceptible to high valent metal ions and results in emulsification.

Non-saponification extracting and separating method for light rare earth element

The invention discloses a non-saponification extracting and separating of method for light rare earth element. According to the method, by virtue of a non-saponification extraction agent (organic phase) comprising an acid extraction agent, an alkaline extraction agent and kerosene, chlorinated light rare earth feed liquid is extracted and separated. Water instead of diluted hydrochloric acid or a high-concentration hydrochloric acid is used as a washing agent and a reverse-extraction agent, the stage retention times of the washing section and the reverse-extraction section are controlled so that the blank organic phase after reverse-extraction can be recycled without eluting the acid entrained in the blank organic phase with water, acidities of effluent liquid in the reverse-extraction section and raffinate in the extraction section are low and the subsequent extraction and separation can be performed without neutralizing. According to the method for separating the light rare earth element, the saponification step is not needed and acidic-basic materials are not consumed, the eluting and acid remove steps of the reverse-extraction organic phase are also omitted and thus the production cost is greatly decreased.
