Pilot experiments to remove lanthanum and cerium ions from model one-component solutions using reagents: opoka, brucite, amorphous silica, thermovermiculite (500 °С, 2 hours), sawdust, thermally activated brucite (600 °С, 2 hours), activated carbon, zeolite, were carried out. Promising sorbents of rare-earth elements of the light group have been identified, which can be used to purify water with a high content of the elements under consideration or in combined sorption technologies for restoring disturbed lands in the areas of extraction and enrichment of rare metal ores.
