India is depleting the mineable gypsum, but has total recoverable cement and plaster grade gypsum reserves of 54 million tons of gypsum (as per 2005). The majority of this is located in Rajasthan (over 97 % of the total reserves). India produced around 16 million tons of gypsum during 2006-2010, an average of around 3-3.5 million t/a.
Gypsum plays a very important role in controlling the rate of hardening of cement. During the cement manufacturing process, a small amount of gypsum (around 5 per cent) is added, in the final grinding process. The rising costs of gypsum has been putting a heavy strain on Indias cement industry in the last couple of years, most of the Indias
Sep 02, 2021 Because it is brittle, it will easily become fine ore to be lost. Due to the high price of the ore, most fibrous gypsum mines adopt the longwall method, selective mining and filling method. The mining techniques of alabaster mine, ordinary gypsum mine and anhydrite mine are similar. The room and pillar mining method (generally 8-12 m in width) and breasting method are adopted. The drilling

Oct 08, 2015 India Rajasthans suspended mining secretary Ashok Singhvi, who was arrested for allegedly running a massive bribery racket, was instrumental in throwing open Rajasthans gypsum reserves, which are the largest in the country, to indiscriminate mining. On 17 August 2014, the mines department headed by Singhvi de-reserved gypsum mining in Rajasthan, ending the exclusive
Sep 02, 2021 The mining techniques of alabaster mine, ordinary gypsum mine and anhydrite mine are similar. The room and pillar mining method (generally 8-12 m in width) and breasting method are adopted. The drilling of gypsum ore is easy, but the explosive consumption is large, generally 0.34 kg/t.

In this process gypsum is crushed, dried, ground, and calcined. Not all of the operations shown in Figure 11.16-1 are performed at all gypsum plants. Some plants produce only wallboard, and many plants do not produce soil conditioner. Gypsum ore, from quarries and underground mines, is crushed and stockpiled near a plant. As

Indias exports of ores and minerals went up by 42% between 2001-02 and 2003-04 an increase mainly due to the rise in exports of cut diamonds and (76% of value of total minerals exported) and iron ore (10.5% of the value), the key minerals exported from India. However, minings contribution to the nations GDP is stagnating at a mere 2.2 ...
In India, gypsum mining is mainly carried out in the state of Rajasthan, which contributes about 99% of the total production. Objective The present study was carried out in 12 different gypsum mines in Rajasthan state to determine the health status of the miners.
The Natural gypsum is mined and extracted below the earths surface using conventional means. In India, natural gypsum is found largely in Rajasthan. Gypsum is also formed as a by-product of the salt manufacturing process and this gypsum is called Marine gypsum. In India marine gypsum is found in Tuticorin and Gujarat where the salt pans exist.
Eventually, there were 13 separate gypsum mine operators in the Grand Rapids area, and by 1890, the citizens of Grand Rapids viewed the gypsum quarries as a mine of apparently inexhaustible wealth to our city. Source The Grand Rapids Press From the beginning, the demand for gypsum was great.

There are four main mining methods underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.
The mixing of sulfuric acid and phosphate creates gypsum (called phosphogypsum) as a byproduct. Although gypsum can be used for a variety of purposes, the EPA prevents usage of Floridas phosphogypsum because it retains low levels of radioactivity found in the host sediments. At present, phosphogypsum is piled up around the processing plant.
The most common method for removing high concentrations of sulfate from water is through addition of hydrated lime (Ca(OH)2), which precipitates calcium sulfate Na 2 SO 4 Ca(OH) 2 CaSO 4 2 NaOH . Calcium sulfate, which hydrates to become the common mineral gypsum, has a solubility of approximately 2000 mg/L as sulfate.
