Gypsum is an evaporite mineral most commonly found in layered sedimentary deposits in association with halite, anhydrite, sulfur, calcite, and dolomite. Gypsum (CaSO 4. 2H 2 O) is very similar to Anhydrite (CaSO 4). The chemical difference is that gypsum contains two waters and anhydrite is without water. Gypsum is the most common sulfate mineral.
Jun 30, 2016· Gypsum as BUILDING MATERIAL Gypsum building materials are used in all construction types (residential, non- residential, new or refurbished), ranging from complex high-tech systems to easy to install products adapted for use by the general public. 15.

The U.S. EPA prohibits the use of phosphogypsum because of the radioactivity. An exception is made for phosphogypsum with an average concentration of less than 10 pCi/g radium which can be used as an agricultural amendment, but for no other use. Phosphogypsum in north Florida has 10 pCi/g radium. Central Florida phosphogypsum averages 26 pCi/g ...
★ Another important use of gypsum is the production of plaster of Paris. Gypsum is heated to about 300 degree Fahrenheit to produce plaster of Paris, which is also known as gypsum plaster. It is mainly used as a sculpting material. ★ Gypsum is used in making surgical and orthopedic casts, such as surgical splints and casting molds.
Nov 08, 2011· Gypsum is a naturally occurring soft sulfate mineral whereas plaster of Paris is a building material that we use for protective or decorative coating purposes. Both these materials contain calcium sulfate as the major constituent.
Nov 19, 2018· Pure white rock gypsum is also known as alabaster and has been used to make carved statues and sculptures. The ancient Greeks used translucent gypsum crystals to make windows. Gypsum powder mixed with water makes plaster of Paris, a molding material used to make ornate fixtures to adorn buildings as well as a coating for walls.
New West Gypsum Recycling began recycling of wallboard waste in Canada in 1985. The recycled material is a blend of pre- and post-consumer, wet and dry gypsum waste that is a source of raw material for use in the manufacture of new drywall products. Gypsum Agri-cycle is one of the first companies to recycle drywall in the USA.

Many structural materials will require underlying gypsum sheathing in order to achieve a good fire-resistant rating, and gypsum board is the most commonly used fire-resistant interior finish. Gypsum board, also known as drywall, consists of a layer of gypsum sandwiched between two sheets of paper.Type X gypsum board is specially treated with additives to further improve its fire-resistive ...
Gypsum is a naturally occurring mineral mined from deposits formed by ancient seabeds as a raw material. Composed of calcium sulfate and water, it is used for a variety of manufacturing, industrial, and agricultural uses. An important property of gypsum is that it is naturally fire-resistant.
Gypsum board is the generic name for a family of panel products that consist of a non-combustible core, composed primarily of gypsum, and a paper surfacing on the face, back and long edges. Various types of Gypsum boards are one of the several building materials covered by the umbrella termed as "gypsum panel products."
A gypsum dryer is commonly used to reduce the moisture content of the ore to the necessary level. The heavy-duty, high volume functionality of a gypsum dryer makes it an ideal drying solution when drying gypsum. In addition, the lifting flights within the rotating drum shower the gypsum through heated air streams, uniformly drying the material as it travels through the dryer.

Gypsum. Gypsum is the aquo-complex whose main component is CaSO4.It is widely used as industrial and construction material. Usually, the gypsum includes plaster stone and anhydrite. Plaster stone is Ca〔SO4〕•2H2O, also known as hydrated gypsum and soft gypsum.
The material is then dewatered and processed; the end product is a consistent, finely divided powder. This process is known as flue gas desulfurization (FGD), and the gypsum produced is known as FGD gypsum. The term FGD gypsum is the name most often used by generators of the material.
Wallboard plants are sited in close proximity to power plants for access to raw material, with a considerable investment involved. Thus, FGD gypsum used for wallboard manufacture is a product rather than a waste or discarded material. This use and similar uses of CCR that meet product specifications would not be regulated under the final rule."
Millions of tons of gypsum are mined each year in North America, and gypsum board is the principal product in which it is used. Besides the newly mined material, up to 20% of the gypsum used to manufacture drywall can be recycled from waste generated at the manufacturing plant or .
Crude gypsum is used as a fluxing agent, fertilizer, filler in paper and textiles, and retarder in portland cement. About three-fourths of the total production is calcined for use as plaster of paris and as building materials in plaster, Keene's cement, board products, and tiles and blocks.
