January 

We formed strategic cooperation with materials-science teams from universities in Jiangxi, focusing on extraction, separation and purification technologies for rare-earth oxides and compounds of cerium, lanthanum, neodymium, praseodymium and rubidium. High-purity single-rare-earth solutions were prepared via neutralisation precipitation, sulphide-precipitation impurity removal and ion-exchange processes. Equipment including reaction kettles, precision filters and ion-exchange columns was upgraded, completing systematic industrial deployment for rare-earth compounds.
