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 ...
Mining can become more environmentally sustainable 1 by developing and integrating practices that reduce the environmental impact of mining operations. These practices include measures such as reducing water and energy consumption, minimizing land disturbance and waste production, preventing soil, water, and air pollution at mine sites, and conducting successful mine closure and reclamation ...

May 27, 2020 Mining remains an essential and growing part of the modern industry. By some estimates, it makes up nearly 45 of the total global economy, and mineral production continues to increase as demand for raw materials grows around the world.. However, many mining techniques still in use can have serious impacts on both the mining site itself and the surrounding environment.
However, mining of iron ore has copious negative impacts on the environment. It degrades natural landscapes, surface and ground water quality, flora and fauna, as well as the ambient air quality within the mining area and its environs. Iron ore tailings usually contain large amount of Silica, iron, and traces of Hg, Se, Cu, Pb, Zn, As, Mn etc.
