environmental effects of mining iron ore

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).
