sources familiar with the gypsum industry. Production The United States continued to lead the world in gypsum production in 2000, accounting for 18.5% of reported global output. During 2000, domestic output of crude gypsum decreased by 12.8% from that of 1999 to 19.5 million metric tons (Mt) valued at $165 million (table 1).
UK consumption of gypsum/anhydrite in 2004 (domestic production of both natural and syn-thetic gypsum plus net imports) is estimated to be 3.9 million tonnes (Table 1). Economic importance Gypsum is a relatively low priced mineral. The value of UK production of natural gypsum has been estimated at £19 million in 2004.
mineral deficiencies, toxicities, and soil character • Adding gypsum to sandy or non-sodic soils is a waste of money, natural resources, and can have negative impacts on plant, soil, and ecosystem health
Gypsum is a hydrated calcium sulfate: CaSO 4 ·2(H 2 O). It is commonly used for making plaster, wallboard and in the production of portland cement. It is commonly used for making plaster, wallboard and in the production of portland cement.
Gypsum Wallboard Production : Wallboard begins with gypsum (calcium sulfate). The mineral is crushed and calcined (baked). Water is added and the liquid slurry is sandwiched between two pieces of paper. After drying, the gypsum wallboard is ready for delivery.
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.
It is an abundant mineral and widely mined. In structural engineering, from a corrosion-technical point of view, contacts of metals and mineral building materials that are produced with cement and gypsum play an important role. Gypsum is a major constituent of backfill materials in cathodic protection.
This statistic shows the global gypsum mine production from 2012 to 2017, by major producing countries. In 2017, Iran's gypsum production amounted to approximately 16 million metric tons. Thus ...
gypsum (jĬp´səm), mineral composed of calcium sulfate (calcium, sulfur, and oxygen) with two molecules of water, CaSO 4 ·2H 2 O. It is the most common sulfate mineral, occurring in many places in a variety of forms.
This statistic illustrates the mine production of gypsum in Mexico from 2010 to 2017 (as of June 2017). In 2016, 5.4 million metric tons of gypsum were produced in Mexico. In the first six months ...
Gypsum industry data for this report are collected by the U.S. Geological Survey (USGS) from semiannual and annual surveys of gypsum operations and from monthly statistics provided by the Gypsum Association in Washington, DC. The 2002 USGS survey, which canvassed 111 gypsum production operations
Oman's Mineral Production: Value: Gypsum data was reported at 11,627.700 OMR th in Dec 2016. This records an increase from the previous number of 9,301.600 OMR th for Dec 2015. Oman's Mineral Production: Value: Gypsum data is updated yearly, averaging 495.000 OMR th from Dec 1996 to 2016, with 21 observations.
Gypsum is a clear, crystal-like mineral, that is generally found in sedimentary rock deposits. It's appearance is the result of centuries of water absorption. In sandy areas, gypsum may develop a …
Gypsum is a non-metallic mineral, found in rock form. It is composed of 79.1% calcium sulphate and 20.9% water, by weight. Chemists call it Hydrous Calcium Sulphate, and as there is one molecule of calcium sulphate combined with two molecules of water.
The most important applications of Gypsum are in the production of plaster, plasterboards, Gypsum fibreboard and Gypsum blocks. The mineral forms the basis of a large industry processing a wide range of building products. Synthetic Gypsum is now more widely used in the manufacture of plasterboard and Gypsum fibreboards.
Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO 4 ·2H 2 O. It is widely mined and is used as a fertilizer, and as the main constituent in many forms of plaster, blackboard chalk and wallboard.
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 produce calcium sulfate hemihydrate (CaSO4 ½H 2O), commonly called stucco.
Gypsum is the most common sulfate mineral. Pure gypsum is white, but other substances found as impurities may give a wide range of colors to local deposits. Because gypsum dissolves over time in water, gypsum is rarely found in the form of sand.

Gypsum is an abundant mineral and takes forms including alabaster—a material used in decoration and construction as far back as ancient Egypt. The White Sands National Monument in New Mexico is the world's largest gypsum dunefield. This non-toxic mineral can be helpful to humans, animals, plant life, and the environment.
Gypsum Rock : Gypsum is an inert, safe mineral that has been used in a variety of applications for centuries. It was used as plaster in the Egyptian pyramids, and today it is most commonly used in homes and commercial buildings, as gypsum wallboard. Gypsum wallboard is a rigid, light-weight building product, valued for its fire-resistant ...

Gypsum: Satin spar, a fibrous variety of gypsum from Derbyshire, England. Specimen is approximately 4 inches (10 centimeters) across. What is Gypsum? Gypsum is an evaporite mineral most commonly found in layered sedimentary deposits in association with halite, anhydrite, sulfur, calcite, and dolomite.
Gypsum is an industrially important mineral. It is the primary ingredient of plaster-of-Paris, which is finely ground Gypsum, and it is used in the production of cement. It is also the main component of sheet rock. It is used as a flux for creating earthenware, and can be used as a fertilizer.
For example, gypsum has been used in the manufacture of assembled cabochons designed to imitate rainbow moonstones. Enhancements. Gypsum can take dyes and coatings very easily. Sources. The most common sulfate mineral, gypsum has many sources all over the world. It occurs especially in evaporite environments.
A non-toxic mineral, gypsum can be helpful to humans, animals, plant life, and the environment. While the majority of gypsum produced in North America is used to manufacture gypsum panels or building plasters, gypsum can also be used:
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.
