    Manufacturing Process Gypsum

    Gypsum, often begins as calcium sulfate dissolved in an isolated body of salt water. As the water evaporates, the calcium sulfate becomes so concentrated that it can no longer remain in solution and crystallizes out (precipitates) as gypsum. Many large beds of gypsum have been formed in this way.
