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.
Impact of Iron Ore Mining on Water Quality . By Abinash Naik. Download PDF (2 ) Abstract. Mining operations require water for their functioning directly and indirectly. Since a long time mining industry has been exploiting water without realizing the adverse impact it is having on the environment and the regional ecosystem.
Old and abandoned mines around the world have harmed water quality long after mining has ceased. Their impacts can come as long-term slow leakage, or as sudden discharges like the 2015 Gold King spill near Silverton, Colorado, which released three million gallons of mine .
