Dirty goethite-a geochemical characterisation of some ...

Channel iron deposits (CID) consist of ferruginous chemical sediments, and are an unusual subset of Phanerozoic coidal ironstone deposits almost unique to the Pilbara, where they constitute around 19 per cent of the Pilbara''s iron ore exports. These deposits occupy many of the ancestral river channels of the Pilbara region, especially the Robe River palaeochannels, incising and meandering ...

Iron Deposits – Banded Iron Formations (BIF) | Geology for ...

 · Banded iron formations (BIFs) are different – they were all formed at a time where the earth was a decidedly different environment than it is today. Banded iron formations are critical to our current economy as they are by far the biggest source of economic iron deposits. BIF from the USA Image: CC. A BIF is hard and heavy sedimentary stone.

Heavy Metals Toxicity and the Environment

Heavy metals are naturally occurring elements that have a high atomic weight and a density at least 5 times greater than that of water. Their multiple industrial, domestic, agricultural, medical and technological applications have led to their wide distribution in the environment; raising concerns over their potential effects on human health and the environment.

IRON-NICKEL (Fe-Ni)

Native Iron is quite often a misnomer as natural iron is not necessarily "native" to Earth since it rarely occurs on the Earth''s surface by terrestrial processes. It is mostly found in the form of meteorites that have impacted the Earth''s surface. A few rare terrestrial gabbros and sulfide deposits do contain elemental iron-nickel deposits, these are the only truly native iron-nickel.
