Some of Oman''s main mineral resources include chromite, dolomite, zinc, limestone, gypsum, silicon, copper, gold, cobalt and iron. Several industries have grown up around them as part of the national development process which, in turn, have boosted the mineral sector''s contribution to the nation''s GDP as well as providing jobs for Omanis.
In 1862, the first mill was constructed at Alabaster, Michigan. Major mining in the Bay area at Alabaster began in the 1860''s, and has since become the most important gypsum mining area in Michigan.

Gypsum mining has a long history in Kansas, dating to the mid to late1800s. The first gypsum deposits worked in the state were near Blue Rapids in Marshall County. Both the Marshall County and Barber County plants have underground mines but the majority of gypsum in Barber County is produced from an open pit.

Generally top slicing is adopted for mining, wherein road leading from entry point of the deposit is prepared and mining is progressed from top to bottom in slices equivalent to the bench height. Face height varies from 10m down to 2m, dependent on gypsum bedding width. The gypsum beds are followed by to 2m of dolomite/limestone.
Gypsum crystals are known for their flexibility, and slim crystals can be slightly bent. (Though trying to bend good crystals is not recommended, as their flexibility is weak, and if flexed too much they will break.) Gypsum has the same chemical composition as the mineral Anhydrite, but contains water in its structure, which Anhydrite lacks ...
What is the Acid Test? To most geologists, the term "acid test" means placing a drop of dilute (5% to 10%) hydrochloric acid on a rock or mineral and watching for bubbles of carbon dioxide gas to be released. The bubbles signal the presence of carbonate minerals such as calcite, dolomite, or one of ...
of interbedded gypsum, dolomite and anhydrite. The gypsum members occasionally crop out on the surface, which is largely composed of gypsum soils. From the top to the bottom the members are the Fortyniner, the Magenta Dolomite, the Tamarisk, the Culebra Dolomite, and the Los Medaños (Figure 1). The Fortyniner member is composed of gypsum,
Mineral textures of samples from nine localities reveal that in these sequences, mineral precipitation follows a recurring pattern: early calcite is followed by anhydrite or gypsum, siderite and/or dolomite. This succession may repeat up to three times.

Dolomite is a mineral composed of calcium magnesium carbonate, CaMg(CO3)2. Dolomite is used as a concrete aggregate and is a source for production of magnesium and glass. The fluidbed dryers/coolers are used for handling materials coming from quarries (dolomite, sand, limestone, gypsum, clay etc.).

Gypsum is a very soft mineral that is easily identified by its hardness, cleavage, and solubility in water. Typically clear to white, gypsum may be colored reddish to brown or yellow if impurities are present. Most gypsum occurs in its massive form, as layers of rock that often intercalate layers of shale, limestone, or dolostone.
Selenite, also known as satin spar, desert rose, or gypsum flower are four crystal structure varieties of the mineral four varieties of gypsum may be grouped together and called selenite. All varieties of gypsum, including selenite and alabaster, are composed of calcium sulfate dihydrate (meaning that it has two molecules of water), with the chemical formula CaSO 4 ·2H 2 O ...

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.

Both gypsum and lime are used as soil amendments. The usefulness of comparing them is limited because their function is different. Gypsum is added to clay and heavy soils to help them drain and improve their tilth, or ability to be tilled, and to remove salt from saline soils. Lime is .
