| titleOfInvention | A kind of extraction and separation method of co-producing pure praseodymium and pure gadolinium |
| abstract | The invention provides an extraction and separation method for co-producing pure praseodymium and pure gadolinium, wherein P507 is used as the extractant, 2N-3N grade gadolinium chloride is used as the first feed liquid, and 2N～3N grade praseodymium chloride is used as the second feed liquid; It consists of fractional extraction and separation of SmEuGd/GdTbDyHoY, fractional extraction and extraction of Pr/NdSm, fractional extraction and extraction of SmEu/Gd and fractional extraction and extraction of Gd/TbDyHoY. Two pure products, 4N-grade praseodymium chloride aqueous solution and 4N-grade gadolinium chloride aqueous solution, are obtained simultaneously in an extraction and separation process. The invention has the characteristics of low acid-base consumption, high stability, high product qualification rate, high green degree, short technological process, low production cost and the like. |
