Dihydrate phosphogypsum (PG) from phosphate fertilizer production plant was considered as secondary raw material to produce gypsum binder. XRD was used to characterize mineral composition of raw material before and after heat treatment, as well as for hardened samples.
wallboard, gypsum must be partially dehydrated or calcined to produce calcium sulfate hemihydrate (CaSO4 ½H 2O), commonly called stucco. A flow diagram for a typical gypsum process producing both crude and finished gypsum products is shown in Figure In this process gypsum is crushed, dried, ground, and calcined.
The results of the study regarding utilization of the waste gypsum formed as a byproduct during the production of the magnesium sulphate from dolomite have been presented. The use of this waste have been proposed for the production of granulated multicomponent fertilizers containing 25% N; 8% S; 14% CaO and % MgO.
