A process is described for making flue gas gypsum from desulfurization of power plant exhaust gas. The process comprises treating the flue gas in a wash tower with a wash water suspension containing calcium oxide, calcium hydroxide or calcium carbonate and converting the scrubbed sulfur dioxide by oxidation with input atmospheric oxygen and by crystallization to calcium sulfate dihydrate crystals.

Gypsum is a mineral found in crystal as well as masses called gypsum rock. It is a very soft mineral and it can form very pretty, and sometimes extremely large colored crystals. Massive gypsum rock forms within layers of sedimentary rock, typically found in thick beds or layers.
Secondly, the rate of growth of gypsum crystals was found to be consistently higher in the vessel than in the pipe flow system. The rate of growth of the pure gypsum in the crystalliser at 25°C was 0.0389 kg/ m2 hour while those in the pipe flow system were between 0.0289 and 0.0202 kg/m2 hour, depending on the pipe material and the scaling solution flow rate.

A larger fraction of SO 3 is added to cement in the form of calcium sulfate, either as gypsum, CaSO 4 2H 2 O, or anhydrite, CaSO 4. During cement grinding, a fraction of the gypsum may be decomposed to hemihydrate CaSO 4 ½H 2 O. The main role of calcium sulfate is to control cement setting, although strength may also be affected.
Gypsum production processand and gypsum typically are mined in a moist or wet condition by open pit excavation or by dredgingfter mining, the sand and gypsum materials are transported to the processing plant by suction pump, truck, belt conveyors, or other
2. Gypsum fertilizer: It is one of the earliest forms of fertilizer used in the United States and it has been applied to agricultural soils for over 250 years. It is a reasonably soluble source of essential plant vitamins, calcium, and sulfur, it might improve general plant
Gypsum usually can be fond in the form of crystals or deposits beds. Gypsum formed in sea basins and lake basins is formed by evaporation of brine or hydration of anhydrite; symbiosis with anhydrite, gypsum, etc. It is layered or lenticular in the interlayer of limestone, red shale, marl and sandy clay.

mineral. Raw gypsum ore is processed into a variety of products such as a portland cement additive, soil conditioner, industrial and building plasters, and gypsum wallboard. To produce plasters or wallboard, gypsum must be partially dehydrated or calcined to 4 2
The setting process involves nucleation and growth of needle-shaped gypsum crystals (2–5 μm in diameter by up to 20 μm in length) that entangle and become interlocked with random orientation. The pore volume between the gypsum crystals consists of interconnected capillaries (∼0.1 μm diameter) that are randomly oriented and filled with excess water during the setting process.
