Gypsum mining and usage creates direct employment for over 500 country people and inceases crop and pasture production by over $300 million annually Gypsum Mining Licences There are currently 77 Gypsum Mining Licences in Victoria covering an area of 3 105 hectares as well as several Gypsum Exploration Licences These Licences are in the
The Cayuga gypsum mine started operation back in 1942 The mine was a late bloomer for the area where the 1800s were the boom years for early gypsum mining Access to a one Meter thick layer of gypsum was encountered in the shaft at a depth of 26 Meters It appears this mine site was in operation for less than a Decade

Multiple runoff connections for groundwater supply and water quality evolution mechanisms were disclosed using hydrochemistry multivariate statistics stable hydrogen and oxygen isotopes and inverse hydrogeochemical modeling in a multi layer groundwater system in a north China coal mining district Groundwater quality was mainly influenced by dissolution
2 Most of the world s gypsum is produced by surface mining operations In 2022 only three underground gypsum mines were in operation in North America one each in Indiana and Iowa in the United States and one in Ontario Canada Gypsum is quarried from near surface deposits Overburden consisting of glacial materials till sand clay shale
In the 1800s several gypsum mines were in operation including the Paris Plaster mine which operated from 1822 to 1905 about a mile south of the town of Paris Ontario The mining was done by digging tunnels from the riverbank Approximately 68 000 tons of gypsum was mined from this location
The potential use and response of dryland soils to management strategies are very much tied to the properties imparted to these soils by the accumulation of carbonates gypsum and silica Thus it is appropriate that the Soil Science Society of America provide the first assessment of the distribution and genesis of these characteristic soil

Environmental Impact of Gypsum Mining Gypsum mining while crucial for various industries poses environmental challenges that must be addressed through sustainable practices and initiatives The process of extracting gypsum can lead to soil erosion water contamination and habitat destruction impacting ecosystems and biodiversity
This chapter looks at the properties of gypsum as a mineral and evaluates its occurrence in soils in relation to related minerals particularly the soluble salts Most of the soils with gypsum belong to the order of Aridisols in Soil Taxonomy and their classification with the recent proposed modifications is presented Their placement in other
Gypsum Mines Blue Rapids KS; The area once boasted four gypsum mines but the Georgia Pacific north of town on 77 is one of only two mines remaining in the state In 1858 Frank Marshall for whom the county is named recognized the rock as gypsum He burned it and produced plaster from the powder which he used to build his house
Data on the distribution of gypsum containing soils in the world their features and the origin of gypsum are presented Sources of sulfur and calcium and the transformation of sulfur containing substances in different moisture and oxidation reduction conditions are examined Detailed descriptions of the forms of gypsum crust gazha granular segregational gypsum pans
Secondary gypsum occurs in soils in a wide range of forms from single crystals in the groundmass to strongly cemented layers understanding the genesis and function of gypsiferous low gypsum and gypseous soils is interesting and challenging and our grasp of processes involved in the formation and behavior of these soils is critical for
