Mining and Water Quality. Mine drainage is metal-rich water formed from a chemical reaction between water and rocks containing sulfur-bearing minerals. Problems that can be associated with mine drainage include contaminated drinking water, disrupted growth and reproduction of aquatic plants and animals, and the corroding effects of the acid on ...
Water quality in a mining and water-stressed region. 2018-1-10 The aim of this study was to determine trends in water quality and mineral footprint along the catchment of a dam located in a mining area and water-stressed region.

Similarly Hire Khan et al., (2002) studied the ground water quality of iron ore mining area in GAO and reported that the ground water in mining area have low pH due to pyretic rocks at the bottom. In few cases of accumulation of water in the pits, the water becomes turbid leading to the contamination of ground water.
Mar 10, 2014 Mine operators extract minerals from underground mines, surface mines and quarries using machinery and explosives. Some extraction processes, such as stone quarries, may use large quantities of water. After extraction, many types of raw minerals are then subject to processes such as crushing, milling, washing and chemical treatments.
Dec 17, 2016 Dec 17, 2016 Types of Water Pollution from Mining. There are four main types of mining impacts on water quality. 1. Acid Mine Drainage Acid Rock Drainage (ARD) is a natural process whereby sulphuric acid is produced when sulphides in rocks are exposed to air and water. Acid Mine Drainage (AMD) is essentially the same process, greatly magnified.
Whereas effect of stone mining and crushing on air quality (Amitshreeya and Panda 2012), soil (Haritash et al. 2007), vegetation (Saha and Padhy 2011), and surface water (Bayram and Onsoy 2015 ...

mining conditions for air and water quality Naturally arid climatic and soil conditions that create conditions favorable for wind and water erosion. However, it is possible to perform qualitative analyses of the environmental impacts of aggregate, stone, and industrial mineral mining for relatively small areas.
Mining and Water Pollution Safe Drinking Water Dec 17, 2016 While there have been improvements to mining practices in recent years, significant environmental risks remain. Negative impacts can vary from the sedimentation caused by poorly built roads during exploration through to the sediment, and disturbance of water during mine construction.
