Iron (III) oxide It is of one of the three main oxides of iron, the other two being iron(II) oxide (FeO), which is rare, and iron(II,III) oxide (Fe 3 O 4), which also occurs naturally as the mineral magnetite. As the mineral known as hematite, Fe 2 O 3 is the main source of the iron for the steel industry.t is of one of the three main oxides of iron, the other two being iron(II) oxide (FeO), which is rare, and iron(II,III) oxide (Fe 3 O 4), which also occurs naturally as the mineral magnetite.

- Iron ore. Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found in the form of magnetite, hematite, goethite, limonite or siderite.

However, there have been some rare blood types discovered which fall out of the A/B Antigen, Rh +/- system normally used to distin … guish blood types.he rarest phenotypic blood type is Type AB negative found in only 0.7% of people worldwide. Genetically the rarest blood type should be Type O; however, it's the most common blood type.

- The most common ore of Iron is haematite Fe2O3. The most common ore of aluminium is Bauxite Al2O3. Although the formulae are very similar, Aluminium is a much more reactive me … tal than Iron and therefore bonds onto the oxygen in the ore much more strongly than Iron does.This means that more energy is required to break the Al/O bonds than the Fe/O bonds and extract the aluminium.lthough the formulae are very similar, Aluminium is a much more reactive me … tal than Iron and therefore bonds onto the oxygen in the ore much more strongly than Iron does.

Rare-earth magnet Rare-earth magnets are strong permanent magnets made from alloys of rare earth elements. Developed in the 1970s and '80s, rare-earth magnets are the strongest type of permanent magnets made, producing significantly stronger magnetic fields than other types such as ferrite or alnico magnets.owever, they form compounds with the transition metals such as iron, nickel, and cobalt, and some of these have Curie temperatures well above room temperature. Rare earth magnets are made from these compounds.

Iron Like other group 8 elements, iron exists in a wide range of oxidation states, −2 to +6, although +2 and +3 are the most common. Elemental iron occurs in meteoroids and other low oxygen environments, but is reactive to oxygen and water.ron reacts with oxygen in the air to form various oxide and hydroxide compounds; the most common are iron(II,III) oxide (Fe 3 O 4), and iron(III) oxide (Fe 2 O 3). Iron(II) oxide also exists, though it is unstable at room temperature.

Iron (III) chloride Anhydrous iron(III) chloride is deliquescent, forming hydrated hydrogen chloride mists in moist air. It is rarely observed in its natural form, the mineral molysite, known mainly from some fumaroles. When dissolved in water, iron(III) chloride undergoes hydrolysis and gives off heat in an exothermic reaction. The resulting brown, acidic, and corrosive solution is used as a flocculant in sewage treatment and drinking water production, and as an etchant for copper-based metals in printed circuit boards.

- The rarest elements in the crust (shown in yellow) are not the heaviest, but are rather the siderophile (iron-loving) elements in the Goldschmidt classification of elements. These have been depleted by being relocated deeper into the Earth's core. Their abundance in meteoroids is higher.

Iron: the essentials For example, it is an iron atom in haemoglobin that is responsible for carrying oxygen around the blood stream. Iron is not found as the free metal in nature. The most common ore is haematite (iron oxide, Fe203). Iron is found in other minerals such as magnetite, which is seen as black sands along beaches. The core of the earth, more than 2000 in radius, is composed largely of iron.

Iron Pure iron is relatively soft, but is unobtainable by smelting. The material is significantly hardened and strengthened by impurities, in particular carbon, from the smelting process. A certain proportion of carbon (between 0.002% and 2.1%) produces steel, which may be up to 1000 times harder than pure iron.

- HFE, the gene for classic hemochromatosis, was discovered by a team of scientists in California 1996. Two major mutations of HFE attributable to iron loading are C282Y and H63D. Numerous prevalence studies support that the C282Y mutation of HFE is common among whites.
