Environmental effects of iron ore mining

of suspended solids derived from Iron Ore Mining. The results from all investigations carried out indicated that the air and water quality of both mining areas are degraded by iron ore mining. Results from elemental characterization revealed harmful trace elements viz. Hg, Pb, Cr, As, Cd, Co. Cu, Fe, Mn, Zn, Ni, Se, Al, Ba, Br, etc

    Assessment of Environmental Impact of Iron Ore Mining

    Thus, Iron ore has been mined for the past three thousand years by ancient and modern mankind. However, mining of iron ore has copious negative impacts on the environment. As the mining method for Iron is usually open cast, it degrades natural landscapes, surface and ground water, flora and fauna, as well as the ambient air quality within the

    Environmental Impacts of Metal Ore Mining and Processing

    May 01, 1997 The impact of mining and smelting of metal ores on environmental quality is described. Mines produce large amounts of waste because the ore is only a small fraction of the total volume of the mined material. In the metal industry, production of Cu, Pb, and Zn causes the greatest degradation of the environment

    On the effects of iron ore tailings micro/nanoparticles in

    Iron ore tailings (IOT) represent a major problem in the mining industry worldwide due to large volumes of waste disposed in mine sites. IOT are exposed to the environment and subjected to wind and water dispersion, even under non-catastrophic scenarios as dam collapses, and the effects of these particles to the biota are still mostly unknown
