nificant amount of phosphorus in raw phosphogypsum is present
in the form of brushite, as was confirmed by XRD patterns
(Roode & Strydom, 1999). Brushite formed similarly to gypsum,
which is not surprising as these are isostructural mineral phases
(see Eq. (7)) (Mikheev ...

XRD analysis
The XRD analysis showed that the most abundant phases in the
PGI and PG2 samples are gypsum (CaSOu:2H5O), brushite
(CaHPOu:2H>SO) and quartz (Fig. 3). These phases have also
been identified in various phosphogypsum samples by various
researchers (Roode & Strydom ...
