Abstract
Geotechnological complex processing of phosphodihydrate, including sulfuric acid leaching, sorption extraction of rare-earth elements, recovery of leaching solutions to obtain rare-earth products and gypsum material, which in the radioactivity and concentration of impurity fluorides and phosphates is suitable for use in building and cement industries, is outlined.
