The mining of iron ore is highly energy intensive and causes air pollution in the form of nitrous oxide, carbon dioxide, carbon monoxide, and sulfur dioxide from diesel generators, trucks and other equipment. The mining of iron ore also causes water pollution of heavy metals and acid that drains from the mines.
world, large quantities of iron ore are also mined in countries such as Guinea, Congo, Sierra Leone and Liberia.9 As with the mining of all minerals, mining for iron ore often creates adverse environmental and social impacts, as well as being linked to fraud and conflict and infringing on the rights of local communities.
Aug 15, 2008 Mining and associated smelting and metal processing activities have led to perturbations in the cycling of metals in the surface environment. In this context, iron-ore mines act as important sources of major metals, mainly Fe and Mn, but also associated trace metals into the environment (Ratha and Venkataraman 1995 Wong 1981 Zabowski et al. 2001).
They also cause noise and surface water pollution, not to mention their effects on the soil and vegetation. Corrosion is another issue observed in iron ore mining; corroded iron ore and pipes at mining sites affect the environment particularly ground water quality. Therefore, there is a need to take mitigating measures.
The environmental impact of Iron ore mining in all its phases from excavation to beneficiation to transportation may have detrimental effects on air quality, water quality, and biological species.    This is as a result of the release of large scale of iron ore tailings ( solid wastes produced during the beneficiation process of iron ...
