The marine gypsum is a by-product of solar Salt manufacturing process. Every Salt manufacturing unit will have marine gypsum deposit in tune of about 5% of their annual Salt production at various stages in various condensers.

Marine Gypsum being heavier (higher in specific gravity) than Salt. Gypsum deposits are found in condensers having Boumie between 17o to 23o. Marine Gypsum gets deposited in the range of few millimeters to centimeters every year and so difficult to harvest.

Usually condensers are harvested once in 3 to 5 years to get sufficient bed-thickness to be able to harvest efficiently. Most of the marine gypsum as being an important ingredient for the grey cement industry is use for cement manufacturing. High quality washed crystal gypsum is also used for plaster of Paris and white cement.
