Effects of iron ore mining on the environment

Aug 15, 2008 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)

    Sep 06, 2012 Sep 06, 2012 Iron is an integral part of the natural environment and many important chemical reactions involve changes in iron that are caused by an electron being transferred to the iron from other minerals, water or biological agents. Electron transfer to iron ( III) oxides creates iron ( II) sites in the mineral. But the iron ( II) site is not fixed, as
