drite/gypsum are blended with cement clinker and finely ground to produce Portland Cement. Additions of about 5% are used to control the initial rate of reaction with water and to retard the setting time of the cement (see factsheet on Cement).

Nonfuel minerals include metals (such as lead, zinc, and copper) and industrial minerals (including limestone, gypsum, iodine, salt, clays, sand, and gravel).Oklahoma metals production is an important part of the state's heritage, but today no mining for metals occurs in Oklahoma.
The mineral Gypsum is chemically named as "calcium sulfate dehydrate".The composition of Gypsum is sulfur attached to oxygen, calcium and water. Gypsum is in abundance; it attains forms like alabaster – the element that was used for construction and decoration which dates back to early Egypt.

Gypsum plaster is a white cementing material made by partial or complete dehydration of the mineral gypsum, commonly with special retarders or hardeners added. Applied in a plastic state (with water), it sets and hardens by chemical recombination of the gypsum with water.
In fact, it is the most common of all sulfate minerals. Gypsum's chemical formula is CaSO 4. 2H 2 O. The anhydrous (without water) mineral is called Anhydrite (CaSO 4). Gypsum and Anhydrite both occur as primary minerals in Marine deposits occur when sea water evaporates under extreme conditions over long periods of time. Gypsum may also be produced by the action of sulfuric .

MINERAL RESOURCES AND MINING. Minerals and mineral products of Texas are presented alphabetically in this article. Aluminum. Three Texas plants produce aluminum oxide from imported aluminum ore (bauxite). Aluminum processing plants are located in Calhoun, Milam, and San Patricio counties. Antimony.
Gypsum is a common primary and secondary mineral of arid and semiarid region soils. Gypsum is by far the dominant sulfate mineral in soils. A saturated gypsum solution at 25C contains ~15 mM CaSO 4, or g/L. It is approximately 100 times less soluble than other common sulfate minerals.
Mining of gypsum is simple and easy, as the mineral occurs in large thick beds near the Earth's surface. However, largescale mining of gypsum involves considerable damage to the environment. Gypsum can also be recycled, but not much importance has been given to recycle this mineral due its abundance.
Gypsum is a mineral (CaSO 4 ·2H 2 O) that occurs in nature as both a mineral and, when in massive form, a rock. Massive deposits are present as sedimentary beds of varying thickness in the subsurface within the Trinity Group in southwest Arkansas.
