Iron ore. Iron doesn''t occur naturally. Being highly reactive, it combines easily with other minerals to form ores. Those with the highest iron content are found near the surface of the earth and are relatively easy to mine. The principal iron ores are hematite (Fe2O3) and magnetite (Fe3O4). Most iron ore is extracted through opencast mines.

Fish kills in 1902 in the Sacramento River, near the city of Redding, were the first documented effects, and shortly thereafter, several private lawsuits and an injunction from the Forest Reserve (precursor to the Forest Service) were served against .
Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3). Iron ore is the source of primary iron for the world''s iron and steel industries.
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.
