The utilization rate of gypsum in sintering was calculated, and the results showed that gypsum decomposition was the limiting factor in the reaction mechanism of calcium ferrite synthesis, the optimal raw material ratio for the formation of calcium ferrite was 30.4% desulfurization gypsum produced in sintering, 31.7% iron ore, 11.1% blast ...Mar 1, 2003 · This phenomenon was attributed to gypsum formation, which was confirmed by X-ray diffraction (XRD). In a study by Tian and Cohen [4], the effect of gypsum formation during sulfate attack on the resulting expansion of C 3 S paste and mortar prisms was investigated. The quantity of gypsum formed in various mixtures was compared by the relative ... Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO 4 ·2H 2 O. It is widely mined and is used as a fertilizer and as the main constituent in many forms of plaster , drywall and blackboard or sidewalk chalk .sulphate (gypsum) scale deposition. The authors have embarked on research project to investigate calcium sulphate scale formation in acidic pH and in the presence of a variety of soluble metals. New antiscalant chemistry for preventing sulphate scale formation in acidic conditions with metals have been investigated and the results are presented.

Dec 28, 2007 · The Castile formation consists largely of anhydrite, which is marked throughout by thin, light and dark laminae that may be varves. 16 These laminae are best seen in well cores, but appear also in all reasonably fresh exposures of the formation, even where the rock has altered to gypsum. The light-colored laminae are relatively pure anhydrite ... Gypsum is one of the most common and troublesome inorganic mineral scales in membrane systems, however, no mechanistic model is available to accurately predict the induction time of gypsum crystallization and inhibition. In this study, a new gypsum crystallization and inhibition model based on the classical nucleation theory and a Langmuir type ...
