Abstract
The gypsum solubility in citric acid solutions of various concentratio ns was studed at 25-90 degrees C. The correlation between the gypsum s olubility in various acids and parameters of its dehydration was used to predict the conditions of calcium sulfate crystallization and parti al dehydration of gypsum into calcium sulfate hemihydrate.
