Get PriceJun 15, 2019Anhydrite Gypsum Contamination. Calcium sulfate contamination is similar to cement contamination because both liberate calcium ions, which in turn cause flocculation. Unlike cement, calcium sulfate does not cause a pH increase since it supplies a sulfate ion in lieu of an hydroxyl ion. The sulfate ion contributes to flocculation of clay solids,
