| titleOfInvention | A kind of method for preparing high-purity lanthanum, high-purity cerium and high-purity praseodymium neodymium |
| abstract | A method for preparing high-purity lanthanum, high-purity cerium and high-purity praseodymium neodymium in the present invention uses light rare earth chloride aqueous solution as feed liquid, and P507 as extractant; it is composed of three fractional distillation extraction systems, which are La/LaCe/CePrNd/ PrNd four-outlet fractionation extraction and separation system, La/Ce full-load two-inlet fractional distillation and extraction system, and Ce/PrNd two-inlet fractional distillation and extraction system. Through the combination of three fractionation extraction and separation systems, three separation products of 5N grade lanthanum chloride, 5N grade cerium chloride and 4N grade praseodymium neodymium chloride are directly obtained. The invention has the advantages of high product purity, high rare earth element yield, low acid-base consumption, short process flow, low separation cost and the like. |
