Abstract
—The values of pH, temperature and initial concentrations of valuable components have influence on recovery efficiency of zirconium and rare earth elements (REE) from pregnant solutions of nitric-acid leaching of eudialyte concentrate by the chemical deposition method. Zirconium and rare earths exhibit selective recoverability of 99.95% and 87.50%, respectively. The loss of REE is 8.0% with zirconium product and 4.5% with pregnant solution. Micromorphology, structural chemistry and chemical composition of products are analyzed using the scanning electron microscopy, IR spectroscopy and X-ray fluorescence analysis.
