Gypsum, one of the most widely used minerals in the world, literally surrounds us every day. Most gypsum in the United States is used to make wallboard for homes, offices, and commercial buildings; a typical new American home contains more than 7 metric tons of gypsum alone. Moreover, gypsum is used worldwide in concrete for highways, bridges, buildings, and many other

This framework is intended to improve sustainability in the quarries and to help to manage biodiversity allowing settingup of appropriate reporting systems in order to maintain the biodiversity status of gypsum quarries. It is a flexible framework adaptable given the local context of each gypsum quarry.

Valuation of Aggregate Operations for Banking Purposes (Sand and Gravel and Crushed Stone) Aggregate consists of sand and gravel and crushed stone. The principal consumers of sand and gravel and crushed stone materials are the highway and building construction industries. The principal construction uses include:
EPA promulgated the Mineral Mining and Processing Effluent Guidelines and Standards (40 CFR Part 436) in 1975, and amended the regulation in 1976, 1977, 1978, and 1979. The regulation covers wastewater discharges from mine drainage, mineral processing operations and stormwater runoff.
extraction site as follows: 0 = sand and gravel pits, 1 = industrial sand quarries or pits, 2 = limestone and dolomite stone quarries and underground mines (plus one sandstone quarry), 6 = clay pits, 8 = peat pits, 9 = tripoli quarries. The last two numbers identify the location of the pit or quarry within each county. For example:
The process starts by extracting gypsum rock deposits from the ground using a ''JOY mine cutter'' that scores away at the face of the gypsum rock. This is then broken up and transported to the surface. It''s homogenising time

The gypsum deposits in the Monferrato area of Piedmont are generally high quality, and underground mining allows the best parts to be reached, favouring extraction of the mineral gypsum without contamination by clay, marl or altered gypsum, as often occurs in opencast quarries.
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/sidewalk chalk, and massive finegrained white or lightly tinted variety of gypsum, called alabaster, has been used for sculpture by many cultures including ...
