- Abstract
Monazite is conventionally processed using caustic conversion and hydrochloric acid leaching in industry, to recover the rare earth elements (REE). Understanding the deportment of uranium decay chain radionuclides is of particular importance for product quality and occupational health and safety (OH&S) purposes. Here, the deportment of uranium decay chain radionuclides during the alkaline treatment route was investigated for the first time, using analytical techniques. Significant quantities of Ra, Pb and Ac were found to report to the rare earth chloride liquor. Subsequent impurity removal treatment generally resulted in the elimination of more than 85 % of radionuclides contained in the chloride liquor.
