Environmental impact of mining

Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes.

The term "iron ore" is one which is used to describe those rocks sufficiently rich in iron to be used economically. Although elemental iron is ranked fourth in abundance in the Earths crust, metallic iron is virtually unknown on the surface of the Earth except as iron-nickel alloys from meteorites and very rare forms of deep mantle xenoliths.

A clearer look at how iron reacts in the environment

· Because iron (II) is more soluble than iron (III), when an electron hops to an iron atom at the mineral surface, that iron (II) atom can be released into solution, and dramatically affect the chemistry and mineralogy of soils and surface waters. Iron reduction is particularly important for the mobility of contaminants in the environment.
