Calcium sulfate CaSO4, is a naturally occurring calcium salt,and It is commonly known in its dihydrate form ( CaSO4∙2H2O), a white or colourless powder called gypsum.

As uncalcined gypsum, the sulfate is employed as a soil conditioner, Calcined gypsum is used in making tile, wallboard.

There are many minerals needed by animals, one of them is calcium that prospers their growth, development and production. Calcium is a main source of formation in the bone and teeth in the animals. Calcium carbonate (ground limestone) is a cost-effective source for animals. Elemental calcium in feed grade limestone is as high as 40%. Our company offered free grade limestone in both, powder and granules forms. Offered as a pure calcium carbonate, its physical characteristics include 90% whiteness
