The main mineral in the gypsum concentrate was gypsum (CaSO 4 ·2H 2 O); however, the brushite (CaPO 3 (OH)·2H 2 O) mineral phase and quartz (SiO 2) were not found. Meanwhile, tiny amounts of muscovite (KAl 2 SiO 10 (OH)) and zoisite (Ca 2 Al 3 [SiO 12]OH) entered the gypsum concentrate owing to mechanical entrainment of the …
