Gypsum that occurs in nature is called mineral gypsum. In addition to mineral gypsum, seawater and some chemical and fertilizer plants are sources of by-product marine gypsum and by-product chemical gypsum, respectively. The latter is obtained as by-product phospho-gypsum or fluoro-gypsum or boro-gypsum, depending upon the source.
May 25, 2012· in water). Mined gypsum is well crys tal lized, having formed over millions of years. Waste gypsum, on the other hand, is formed rapidly during industrial processes and is less crystallized. Although they have the same chemical formula, the waste gypsum materials dissolve more rapidly than mined gypsum. Sometimes powdered gypsum
A. Chemical weathering speeds up physical weathering by weakening the rock B. When different rocks in an outcrop undergo weathering at different rates it is called differential weathering C. Weathering happens fastest on the flat faces of broken blocks of rock D. Physical weathering speeds up chemical weathering by increasing surface area

Jul 30, 2010· Synthetic gypsum is also called flue-gas-desulfurization (FGD) gypsum. It is produced through a chemical reaction in the chemical scrubbers that remove sulfur from the flue gases of coal-fired power plants. Sulfur dioxide from power plants is the leading cause of acid rain, and the Clean Air Act of 1970 required power plants to reduce their ...
Phosphogypsum Stacks. America is blessed with abundant low-cost natural gypsum. There is also an abundance of flue gas desulfurization gypsum produced as a by-product of coal-fired power plants. As a result, the market for the phosphogypsum generated by the chemical processing of phosphate rock has traditionally been limited.
