Gypsum and Salt Mining in Central Hupeh, China

cheng district has produced gypsum for about four hundred years and the mining field has narrowed to a compact area ly-ing just northwest of the county town of Yincheng. Salt also is produced by the same mines that produce gypsum, but salt production dates only from the 1860's. The country about Yincheng is roll-ing in surface, with but slight relief and

Environmental impacts of the gypsum mining

2001-11-1  The impacts of quarrying of the gypsum deposits on the environment at Maqna, Tabuk, were evaluated by intensive field studies including in situ testing, mapping and sampling of gypsum and well water. Field and laboratory tests were made to determine the engineering properties including tensile and compressive strengths, unit weight, fracture spacing and the rock quality designation (RQD) values.

The British Gypsum mining process

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

Hydrogeological conditions of gypsum rock masses are also very relevant for exploitability, safety conditions and economic feasibility and should be accurately known during the prospection and planning phases of the quarries. In this work, a relationship between electrical resistivity and saturation degree of gypsum is proposed.

2021-3-10  Gypsum used for plaster manufacture usually contains at least 90% CaSO 4 2H 2 O, a maximum of 0.02% NaCl (salt), and approximately 2% acid insolubles. Another major use of gypsum is in the cement industry, where it is added at the rate of 2–5% to cement clinker prior to final grinding to retard the setting rate of concrete.

Deep below the rugged surface of Indiana's Martin County people work in two underground mines to extract and process an unusual mineral resource - gypsum. Gypsum (CaSO4*2H2O) is a soft, water soluble mineral that is processed to make critical building materials especially wallboard. Gypsum is mostly massive (Figperiod; 1A) but also forms silky satin spar (Figperiod; 1B).
