Red gypsum can be considered as a long term storage of carbon dioxide through mineral carbonation. However, for the efficient carbonation, the calcium ions need to be extracted in the solution phase, followed by the carbonation reaction. Therefore, the extraction step is the key of successful mineral carbonation.

Gypsum Mining. IMAR 7 th Edition. Most of the world's gypsum is produced by surface-mining operations. In the United States, gypsum is mined in about 19 states. The states producing the most gypsum are Oklahoma, Iowa, Nevada, Texas, and California. Together, these states account for about two-thirds of the United States' annual production ...
The extraction processes have already taken a heavy toll on them." They also demanded that the grazing land should be kept free for livestock so that "only source of income for many families is ensured in the long run." Experts say that gypsum mining can lead to …
Illegal extraction of gypsum: Documents show that the Mines and Petroleum Department in a letter to Baghlan governor's house in April 2016 said that gypsum from the Sheikh Jalal Gypsum Mine was illegally extracted by gypsum processing factories.
Mining activities are a potentially important contributor to water contamination. Discussions in the literature on impacts of gypsum mining on water quality are not conclusive because they tend to be site specific and lacking in details. This study sought to establish the impacts of gypsum extraction activities on water quality in Kajiado.
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. It has the chemical formula CaSO 4 2H 2 0. By volume this works out to nearly 50% water in ...
underground mining is the usual method of extraction, the mineral normally being within 60 metres of the surface. Method of Working and Environmental Impact Opencast Extraction of the Newark Gypsum 10.5 Extraction begins with the creation of an initial cut which needs to provide adequate space to develop and work the quarry face.

We found that the cyanobacteria attached onto high surface energy crystal planes ({011}) of gypsum samples generate a thin biofilm that induced mineral dissolution accompanied by water extraction. This process led to a phase transformation to an anhydrous calcium sulfate, anhydrite, which was formed via reprecipitation and subsequent attachment ...

It is an important part of the Canadian economy, both from the side of extraction in the mining process to the final use after processing. Today, nearly 75 percent of Canadian production of gypsum is based out of Nova Scotia.
Furthermore, gypsum is a mineral in global demand (Herrero, Escavy, & Bustillo, 2013), and its extraction by mining inevitably damages valuable gypsum habitats (Chapin, Sala, & Huber-Sannwald, 2001; Mota, Sánchez-Gómez, & Guirado, 2011). Thus, mining companies are usually compelled to conduct restoration programmes despite the lack of ...
