impurities are present. The red gypsum has a much lesser value but is sometimes sold as soil additive. Waste acid from the hydrolysis of titanyl sulfate is not strong enough for direct reuse in the process. The mixture includes 20 - 23% sulfuric acid as well as residue water and impurities such as iron sulfate (FeSO 4). The addition by-product from the wet process phosphoric acid, and the rest by direct neutralization of sulphuric acid by ammonia. However, with the commencing of the new cement plants, the consumption of gypsum in the cement industry would increase in the next five to six years. 0.6 Calcined gypsum finds use in the plasters and manufacture of plaster of paris.
