	Limonite - Wikipedia, the free encyclopedia
		It is not a true mineral, but a mineraloid, and it is composed by a mixture of similar hydrated iron oxide minerals, mostly goethite with lepidocrocite, jarosite, and others.
		Iron caps or gossans of siliceous iron oxide typically forms as the result of intensive oxidation of sulfide ore deposits.
		These gossans were used by prospectors as guides to buried ore. In addition the oxidation of sulfide deposits which contained gold mineralization often resulted in the concentration of gold in the iron oxide and quartz of the gossans.

	"B11B-1029" in fm06
		Dissimilatory iron reduction at high temperatures is likely to be widespread in high-temperature, anoxic environments such as deep-sea hydrothermal vents and terrestrial hot springs.
		In P. aerophilum, ferric reductase and nitrate reductase activities and nitrate reductase abundances varied in iron- and nitrate-grown cultures suggesting that dissimilatory iron and nitrate reduction are regulated.
		This suggests that direct contact with insoluble iron was not necessary for growth and that the organism may use an extracellular mediator for iron reduction.

	Alpha iron (III) oxide crystals and derivatives - Patent 4006090
		Gamma iron oxide particles produced by the oxidation of the magnetite particles of claim 4 and having the shape, size and fine structure of the hematite particles of claim 1 and having magnetic coercivities of from 196 to 306 oersteds, saturization megnetizations of 66-71 e.m.u./gram and squareness ratios (.delta..sub.r /.delta..sub.s) of 0.32-0.38.
		The magnetic iron oxides derived from the hematite particles of the invention are novel by reason of their morphology, which remains essentially unchanged during the reduction and reoxidation of the hematite particles.
		That is, the magnetic oxide particles have the shape, size and fine structures of the parent hematite particles but consist chemically of either magnetite or gamma iron oxide.

	The chemistry of steelmaking. The big picture.
		Most workable iron ores are rich in iron (III) oxide, Fe Making iron by removing oxygen from the ore is the first step in the manufacture of steel.
		The overall process is a redox reaction, in which iron (III) oxide is reduced and carbon monoxide is oxidised.
		Between 20% and 30% of the iron is produced by direct reduction, when the ore is directly reduced by carbon.

		In the crust the free metal is rare, occurring as terrestrial iron (alloyed with 2-3 percent nickel) in basaltic rocks in Greenland and carbonaceous sediments in the United States (Missouri) and as a low-nickel meteoric iron (5-7 percent nickel), kamacite.
		Limonite and hematite are the chief iron ores.

		It was cheaper to move iron to the iron works than to move the vast amounts of charcoal needed.
		Iron pyrites, or fool's gold, cannot be used to make iron because of its high sulphur content which makes the iron too brittle.

	Iron(III)oxide
		Since some iron alloys, (like cast iron) can contain carbon and silicone (not soluble in the acid), these can be easily separated by filtration when iron have been dissolved.

		However, that is to prepare analytical grade iron oxide.

	Rust
		The problem with iron as well as many other metals is that the oxide formed by oxidation does not firmly adhere to the surface of the metal and flakes off easily causing "pitting".
		This is possible because the electrons produced via the initial oxidation of iron can be conducted through the metal and the iron ions can diffuse through the water layer along the metal surface to another point on the metal surface where oxygen is available.
		This is one reason why iron or steel tend to corrode much more quickly when exposed to salt (such as that used to melt snow or ice on roads) or moist salty air near the ocean.

		X-ray diffraction analysis confirmed that the iron(III) oxide in the prepared Fe-Si adsorbents was amorphous, largely due to the retardation of the iron oxide crystallization by the presence of silicate species.
		These forms of iron(III) oxides retain their strong affinities to As(V) and As(III), but are limited to reactor configurations incorporating large sedimentation and filtration units, which cause difficulty in solid/liquid separation [18].
		Since the crystallization of iron oxides, for instance, the transformation of ferrihydrite to goethite, is strongly retarded by the presence of silicate species [20-23], the FeOOH formed through co-precipitation with silicate should be in an amorphous (or poorly crystalline) form.

		If iron is heated in the presence of less oxygen, it is possible to synthesize another iron oxide, Fe, called magnetite.
		It could be that one of the two irons is neutral and the other is +6e, or maybe both are +3e, or maybe even one is –10e and the other is +16e, for all we know now.
