Gypsum is one of the more common minerals in sedimentary environments. It is a major rock forming mineral that produces massive beds, usually from precipitation out of highly saline waters. Since it forms easily from saline water, gypsum can have many inclusions of other minerals .
SIGN OF ELONGATION (X-POLARS)—Determine the sign of elongation if possible (the mineral must be elongate or have a pronounced cleavage and be slightly enlongated). Use the gypsum plates to determine the sign of elongation for any minerals that have an elongated crystal habit (Mica plate - quarter wavelength for first order birefringences).

May 17, 2011· A General Overview in Mining Industry. Albania is a country with rich mineral resources. Mineral exploration, exploitation and processing constitutes a key component of the Albanian economy, due to a traditional mining industry that has been a solid foundation to the country economic sector generating substantial revenues.
Gypsum, but is comparatively limited in its technical applications. The content of Gypsum in sedimentary rock varies from 75% to 95%, the rest being clay and chalk. B. Extracting Natural Gypsum Gypsum/Anhydrite are produced from open-cast mines, or underground mines using pillar and stall mining methods, that give extraction rates of up to 75%.

These minerals should be handled/moved as minimally as possible, and stored in the dark – they will otherwise turn to powder before long. Even so, exposure to air plays a role in the process, but looking after them the best we can will at least prolong their existence as stable mineral specimens.
Gypsum is a common mineral, with thick and extensive evaporite beds in association with sedimentary rocks. Deposits are known to occur in strata from as far back as the Archaean eon. Gypsum is deposited from lake and sea water, as well as in hot springs, from volcanic vapors, and sulfate solutions in veins.
Properties and Uses of Gypsum ScienceStruck. 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 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.
Anhydrite converts to gypsum when exposed to water, which creates a volume increase that destroys any planar features in the beds. The reverse is also possible—anhydrite can be created when gypsum is dehydrated. Both minerals display vitreous luster and are white in color and streak. The calcium in either mineral may be
Find the hardness compared to the hardness of other minerals to find which mineral scratches what, has cleavage/fracture or is metallic or no nonmetallic. Which common objects will scratch feldspar? Steel file, streak plate ... What is the hardness of a mineral that scratches gypsum but cannot scratch calcite?
Pseudomorphs of gypsum after an unidentified mineral [Clark, 1993 - "Hey's Mineral Index"]. Satin Spar Gypsum: A fibrous variety of Gypsum. See also the main page on Satin Spar. Selenite: The name 'selenite' is mostly synonymous with gypsum but has been used historically to describe the transparent variety, as opposed to satin spar gypsum for ...
In 2012, their production reported production of 99.99% pure copper metal cathodes. Mineral commodities that have been mined include asbestos, bentonite, chromite and sulfide minerals, as well as stone products including cement, gravel and sand. Other marketable minerals including clay, gypsum, lime, ocher and umber production have been recorded.
A gypsum mine in a particularly thick deposit had almost a cathedral-like air upon depletion, because of the towering columns and arches of mineral remaining. Only one example of this sort of gypsum-mining remains in Paris, in a renovated "grotto" under the Buttes-Chaumont gardens.
Gypsum, common sulfate mineral of great commercial importance, composed of hydrated calcium sulfate. It occurs in extensive beds associated with other evaporite minerals, particularly in Permian and Triassic sedimentary formations; it is deposited from ocean brine, followed by anhydrite and halite.
The very extensive gypsum and anhydrite deposits have been exploited in relatively few places. Economic factors, rather than quality of the deposits, may delay or prohibit actual mining operations. Even the unworked and unworkable deposits are beneficial in other ways, however.

(It is debatable whether these green crystals are natural or are formed from acid runoff from mining operations.) Exceptional, bright orange crystals of Gypsum come from the salt mine of Las Salinas de Paracas, Pisco, Peru. Mexico boasts the most notable and finest localities of this mineral.
