FIELD: construction.
SUBSTANCE: phosphogypsum processing method includes the phosphogypsum supply into the silo, then its grinding and introducing of additives, while after the silo the phosphogypsum goes for grinding into the hammer crusher, then it is mixed with water and sorbent - finely divided tuff in the amount of 0.1-3.0 % from the phosphogypsum mass and using the technological pumps the received suspension goes to the vortex layer plants for processing in the rotating magnetic field with ferromagnetic particles, then goes into the decanting tanks, where the coagulation and deposition of the suspended particles into the sludge occurs.
EFFECT: phosphogypsum recycling, getting the certified calcium sulfate dihydrate.
