Iron atoms arrange themselves in one of two stable crystal structures called the bodycentered cubic structure and the facecentered cubic structure. The bodycentered cubic structure of iron, which is called ferrite, is stable at (i) a temperature of 1,665K (1,392 ) or above and (ii) at 1,184K (911 ) or below, the crystal forms being referred

The study aimed at investigating the chemical composition and microstructure of raw iron ore from the deposits in Muko area (southwestern Uganda). The quality of this iron ore was evaluated to establish its suitability to serve as a raw material for iron production. Samples were taken from the six hills of Muko ore deposits and tests carried out to establish their composition and properties.

Iron compounds are produced on a large scale in industries. Ferrous Sulfate, FeSO 4 7H 2 O and Ferric Chloride, FeCl 3 are two of its compounds which are produced on a very large scale. One of the chemical properties of iron is that it easily gets oxidized in open air, and this is why many compounds of iron (II) get oxidized into iron (III).

· Iron ore is the primary raw material used to make steel. Steel is strong, longlasting and costefficient – making it perfect for everything from washing machines to cars, bridges and skyscrapers. According to the World Steel Association, steel is the most commonly used alloy in the world.

Iron is the backbone of the world we have built around us and it is the basic ingredient of steel (iron plus carbon). Iron is a very useful metal because it can be mixed with other metals to make a whole variety of ''alloys'' which are even stronger and don''t rust easily and can be shaped into products from cars to pins, appliances to buildings, bridges to railways, food cans to tools.

The primary use of iron ore is in the production of iron. Most of the iron produced is then used to make steel. Steel is used to make automobiles, locomotives, ships, beams used in buildings, furniture, paper clips, tools, reinforcing rods for concrete, bicycles, and thousands of other items. It is the mostused metal by both tonnage and purpose.

Mining Mining Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on the

Bog iron ore is limonite or goethite, deposited with the aid of iron bacteria in anaerobic swamps. The iron is carried in by waters containing CO 2 as soluble bicarbonates. The organic matter reduces it to oxides, which make characteristic iridescent patches on the water, then precipitate on the bottom of the marsh to form an ironrich layer.

Steelmaking relies on iron ore and metallurgical coal as main ingredients, the trade of which is hypothesized to theoretically change in tandem. However, strong correlation is not evident in historical trade prices of steelmaking inputs. To determine causes to this occurrence, the market factors that influence the Australian iron ore and metallurgical coal industries were studied.
