Decomposition of a Lean Yttrofluorite Concentrate by the Method of Sorption Conversion
摘要
The behavior of rare-earth elements and major impurities during the nitric-acid decomposition of a lean yttrofluorite concentrate by the method of sorption conversion is studied. The decomposition conditions providing satisfactory extraction into the sorbent for rare-earth elements, especially yttrium and yttrium group lanthanides, are determined.
