Increasing iron ore demand, coupled with the depletion of highgrade hematite ores in the United States, after World War II led to development of lowergrade iron ore sources, principally the utilization of magnetite and taconite. Iron ore mining methods vary by the type of ore being mined.
Iron ore prices have fluctuated over the past decade. Prices declined from a high of US187 per tonne in February 2011 to a low of US41 in December 2015. During 2016, iron ore prices were stable until March, when they began to rise, and ended the year at US per tonne.

#0183;#32;Mining and associated smelting and metal processing activities have led to perturbations in the cycling of metals in the surface environment. In this context, ironore 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).
Iron ore being unloaded at docks in Toledo, Ohio. Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, % Fe), hematite (Fe 2 O 3, % Fe), goethite (FeO(OH), % Fe
