Genotoxic impact, i.e. the level of primary DNA damage in haemocytes, was also investigated, since gypsum mining activities result in wastewaters contaminated with heavy metals. For this purpose, water and sediment samples and amphipods were collected at a site downstream from a gypsum mine, in the Kosovčica River, and at a reference …
Nitrification is the core step of the soil nitrogen cycle and directly affects the nitrogen use efficiency in agricultural systems. Biochar and gypsum are two important soil amendments widely used in coastal saline farmland. However, little is known about their effects on nitrification and ammonia-oxidizing microorganisms.

Texas industrial minerals from 2000 through 2015. Other includes the combined values of all clays, dimension stone, gypsum, helium [crude, grade-A (2000–12)], silver ...
– The Bureau of Land Management has released the Final Supplemental Environmental Impact Statement (EIS) for the proposed expansion of the US Gypsum Mine and associated water lines in southwestern Imperial County. The Final Supplemental EIS provides a comprehensive analysis of the potential environmental impacts of the …
Discussions in the literature on impacts of gypsum mining on landscape are site specific and lack in details. This study sought to establish the impacts of gypsum mining activities on landscape in ...
Explore the environmental impact of gypsum mining: water contamination, soil degradation, and air pollution risks. Discover sustainable practices and regulatory frameworks for a greener future in mineral extraction.
Since 1956, Harrison Gypsum has been a prominent figure in the gypsum mining sector. The company has made a name for itself by maintaining a consistent and high level of product quality. They operate four gypsum mines in Oklahoma, one mine in North Texas and three limestone mines – two in Oklahoma and one in South Kansas.
The discard and landfill of by-product gypsum cause significant environmental problems. About 100–280 million tons of phosphogypsum and a large amount of waste …
The results show that (1) during repeated contact of the three types of industrial waste gypsum with the leaching medium, the pH levels changed, and the …
A thorough research into the specific impacts of gypsum mining on landscape was a necessity and the study sought to address this gap. The overall objective of the study was to identify and assess the impacts of gypsum mining on the landscape at the mining sites in Kajiado County, so
the economic, social and environmental impacts of the gypsum mining on people living nearby as well as at the national level. However, given the non-existence of economic and social data on the communities, the impacts outlined in the study are mostly perceived ones. Part 2: A brief background of Khothagpa gypsum mine The gypsum mine is …
Gypsum extraction was dominated by open cast mining and manual quarrying methods, which involved the removing of top soil up to the bedrock, effectively making the mining …
Mining is a crucial industry — from iron and copper to gravel and sand, we depend on it for the basic building blocks of the modern world. It is a fast changing sector, as the clean energy ...
Gypsum mining can lead to various environmental impacts. The extraction process often involves clearing large areas of land, resulting in habitat destruction and loss of biodiversity. The removal of vegetation and …
However, mining activity does not necessarily mean loss of biodiversity and danger for ecosystems. The gypsum mines managed by CertainTeed, a Saint-Gobain company, commit daily and on the field to the conservation of nature and preservation of biodiversity by bringing constructive solutions to the environmental impacts of gypsum quarrying.
tal impact parallelly to the mitigation of PHE hazards. Abstract Purpose Soil pollution is a major problem worldwide. Some anthropogenic activities, such as mining, may ... soil and gypsum mining spoil, with the aim of assess-ing for the rst time the potential use of gypsum min-ing spoil to enhance soil properties, to reduce PHE ...
1. Introduction. As typical brittle rock masses, gypsum mines are often produced in the form of thick and large layers with good integrity and excellent stability; therefore, room-and-pillar mining is often used [].In the production process of the mine, the multilevel goaf left by in the room-and-pillar mining method exhibits good stability …

Calcium Sulphate Dihydrate (Gypsum) is commonly hydrated by groundwater. The UK is largely self-sufficient in gypsum. The material can be found in seams in the Pennines and the Midlands, but the biggest source of extraction is in East Sussex where mining extracts some 100,000 tonnes of gypsum a year from 100 m below the High Weald.
