The Mechanism of Influence Exerted by Integrated Energy Impacts on Intensified Leaching of Zirconium and Rare Earth Elements from Eudialyte Concentrate

Abstract

The article gives test data on the influence exerted by energy impacts (ultrasonic, electrochemical and thermal) on the recovery of zirconium and rare earth elements from eudialyte concentrate to leach solution in acid leaching. An original installation is developed for the implementation of leaching. Based on the research findings on the kinetics of acid leaching of eudialyte concentrate and on the change in the concentrate micro-structure and phase composition, the mechanism for the influence of integrated energy effects on the efficiency of recovery of zirconium and rare earths into leach solution is substantiated.
