The yield of REM transfer into phosphogypsum is up to 98%.
Process of two crystallization stages for reducing radioactive contamination of phosphogypsum.
The gypsum or phosphogypsum is preferably added in an amount from 2 % to 10 % relative to the total weight of raw materials.
As for the plasters containing phosphogypsum, some present a risk of radioactivity, which comes from the basic ore from which the phosphogypsum is extracted, ore sometimes accompanied by uranium.

The depleted phospho gypsum is preferably treated in a further step to reduce any remaining water soluble P2O5 to a level which allows the gypsum to be added to a cementitious material for use as a setting regulator.
Hundreds of people demonstrated in the Tunisian city of Gabes against the environmental pollution generated by the phosphogypsum discharged into the sea by phosphate processing plants.
