Pilot-industrial installation of processing phosphogypsum in continuous mode of operation for extracting rare-earth and other impurities and production of raw material for production of binders building materials has sorption system of 4-8 sorption columns with sulphocationite, interconnected in series and with the possibility of independent cyclic switching of each column with sorption on desorption. Installation allows to process up to 2 tons phosphogypsum day and to separate from 50.8% to 83, 2% valuable impurities rare-earth, and also to produce qualitative raw material for production of binders building materials, purified from interfering impurities. 1 nezavis. u. claim, 1 to.
