Study of the Layering Process in Extraction Systems for Optimization of the Technology of Rare Earth Elements Production

摘要

Effect of the contents of non-rare-earth admixtures, in particular calcium, and of the concentration of nitric acid in initial solutions on the rate of layering emulsions was studied the model extraction systems tributyl phosphate, nitric acid REE solutions. The opportunity to reduce areas of settling chambers by a factor of 4-5 at the subsequent steps of the separation and production of individual rare-earth elements.
