A clearer look at how iron reacts in the environment

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 The iron ore market has shaken off concerns environment restrictions in China would curb the rally in prices, with tight price conditions expected to persist through the rest of the yearIron ore shakes off China production restrictions The environmental consequences of mining Iron Mountain became apparent only a few years after the start of open mining in 1896 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 US Forest Reserve (precursor to the Forest Service) were served against Environmental Effects of Mining Iron Mountain USGS
