Presently, there is widespread global interest in the area of mining and its sustainability that focused on the need to shift mining industry to a more sustainable framework. The aim of this study was to systematically assess all possible environmental and climate change related impacts of the limestone quarrying operation in Thailand.
Limestone comes in many different varieties. Chalk is a very fine grained, porous marine limestone composed almost entirely of microscopic fossils. Travertine is a freshwater sedimentary limestone that has very thin, crenu-lated layers and is commonly formed at springs. Marble is a carbonate rock, usually a marine limestone, that has been

Limestone, a seemingly ordinary rock, holds extraordinary significance in modern society.Its versatile nature and wide-ranging applications across numerous industries often go unnoticed by many. However, looking deeper into its uses reveals a mineral that plays a vital role in agriculture, manufacturing, environmental remediation, healthcare, and beyond.
The limestone mined is used chiefly for the manufacturing of cement, lime and edible lime etc. Scientific studies revealed that loss of forest cover, pollution of water, soil and air, depletion of ...
In the current research, isothermal experiments of kinetic analysis were performed at different temperatures (800–1050 °C) and particle sizes (885 to 10,763 μm) to investigate the calcination kinetics of high-purity limestone. Thermal analyses were carried out in a zirconia crucible, 1 cm in height, for different temperatures and particle sizes. The reaction rate …
Limestone extraction is strategic for the provision of materials for the entire construction sector. The extraction activities are also source of huge impacts on the natural environment and the landscape as well as on human health (Clemente et al., 2004; Agboola et al., 2020).However, if such activities are performed according to the most recent legislation …
The present study is based on the impact of Kota stone or limestone mining on water resources. Among those villages and census towns, experiencing mining activity, a total of 26 surface water and ...
Commercial production of limestone throws multifaceted challenges that need to be solved by applying scientific planning and emerging technologies. While assessing the mineral deposits, …
The objective of this research is to mine the limestone in such a way that the resulting raw mix meets both quality and quantity specifications of the cement plant. The primary requirement for developing an acceptable raw mix for cement plant is calcium oxide
In limestone mining, the waste deposit ratio is too high. To minimize waste extraction activities, hyperspectral remote sensing imagery utilized to identify the purest form of calcite in the examination area. This report reviewed papers on the possible impacts of the mining region's limestone quarrying activities on the atmosphere and climate ...
This study investigates the roof stability of underground limestone mining in the presence of stratified joints during the excavation process. An analytical solution is derived to predict the stresses and deformation of underground tunnel structures, with the structure simplified as a double-hinge arch. The accuracy of the analytical model is validated through …
Major energy sources for limestone and other crushed rock include fuel oil and purchased electricity. In 1992, rock mining consumed 66.8 Btu. Table 9-1 shows the type and quantity of …
The current trend of limestone mining in the Indian mineral industry harnesses emerging technologies to redefine and reinvent solutions that suit production optimization and …
The following lists the inputs and outputs for limestone and other crushed rock mining and processing. Key inputs and outputs are: Inputs Electricity Fuels Water Outputs Dust Waste Water Carbon Dioxide Figure 9-1 illustrates the steps in limestone and other crushed rock mining and processing with the inputs and outputs. Crushed Rock 9-4
Limestone mining in East Jaintia Hills, Meghalaya, India is being carried out extensively for the production of cement. Extraction of limestone is done mainly by adopting opencast method of mining ...
Acid Mine Drainage (AMD) has the characteristics of high heavy metal ion content and low pH. This study aimed to synthesize the CaO/Fe3O4 composite for the adsorption of iron and manganese ions ...
Limestone mining causes widespread disturbance in the environment. Myriad impacts are observed as changes in land use pattern, habitat loss, higher noise levels, dust emissions and changes in aquifer regimes. These environmental concerns have brought about the need for sustainable Environment Management Plan in the mining sector, so as to ...
8 Environmental Hazards of Limestone Mining and Adaptive … 125 8.3.1 Impacts on Land and Soil Opencast mining has been associated with a change in land use and land cover of
Chemical limestone forms when calcium and carbonate ions suspended in water chemically bond and precipitate from their aquatic sources. Because of its high calcium content, limestone is …
From 2000 to 2020, open-pit mining at the Wulishan limestone mine in Anhui Province, China, increased the area of direct vegetation destruction by 9.072 × 10 5 m 2, and the indirect impact area on vegetation was 7.371 × 10 5 m 2. The carbon emission cost of vegetation destruction in the direct destruction area was about 104,000 yuan per year ...
Limestone mining isn't discussed as often as, say, fracking or oil drilling, but it has its fair share of risks and problems. Let's look at six top limestone mining issues. 1. Groundwater Contamination. Limestone is mined underground, but vital groundwater is located underground too. When there is a limestone mine near a groundwater source ...
Limestone is found near the surface (called a surficial deposit); hence, it is produced mainly from surface mines.By and large, limestone is mined by two methods: opencast stripping for hilly deposits and open-pit mining for plain deposits. To meet the industrial requirements of a large country like India, medium- and small-sized mines of various types …
