METHOD OF PREPARING MELT CONTAINING POTASSIUM CHLORO-ZIRCON ATE AND FLUORIDE OF RARE-EARTH ELEMENTS

摘要

FIELD: metallurgy of rare-earth metals; production of melts of salts of potassium chloro-zircon ate used for electrolytic and metal-thermal production of zirconium. ^ SUBSTANCE: proposed method includes introducing potassium and sodium chlorides into melt. For obtaining melt containing fluorides of rare-earth elements, potassium fluoro-zirconate is introduced into melt in zirconium compound and anhydrous chloride of rare-earth elements is introduced at temperature of 680-700 C for exchange reaction between potassium fluoro-zirconate and chlorides of rare-earth element. ^ EFFECT: increased degree of extraction of zirconium and rare-earth elements. ^ 2 ex
