Phosphogypsum. Phosphogypsum, a waste by-product from wet-acid production of phosphoric acid, contains variable levels of metal impurities (Cd, Zn, barium (Ba)) and radionuclides (mainly uranium (U), thorium (Th) and radon (Ra)) depending on the composition of the phosphate rock and efficiency of the wet-process used (Rutherford et al., 1994).

Phosphogypsum (PG) is a by-product generated from the phosphorus fertilizer industry (phosphoric acid production). PG is similar to natural gypsum, but there are some differences, of which it contains some impurities such as water-soluble phosphate (P 2 O 5), water-soluble fluoride (F −) and P 2 O 5 substituted in the gypsum crystal lattice.

Phosphogypsum (PG) is a by-product of CPF production via the wet-process phosphoric acid technology . The current global production of PG is estimated to be 100~280 Mt per year . PG is usually acidic (pH value 2–4) and could contain toxic elements (heavy metal cations, fluorine, etc.), which are hardly reused (less than 40%) .
