Mining provides essential raw materials for an industrialized society. However, it causes serious pollution of surface and groundwater. Transferring minerals from deep below the surface to the surface promotes oxidation reactions. Oxidation of iron salts and of sulfur-containing materials in the presence of water leads to highly acidic solutions.

Iron ore is rock which metallic iron can be extracted from. Iron ore is the most common element in the world and makes up close to 5% of the Earth's crust. This makes it one of the most abundant rock elements. Iron ore that contains a high quality of hematite or magnetite are known as "natural ore" and they can be entered directly into blast furnaces that produce iron.
