Iron Ore Deposits in Agbaja Area by Olatinpo O.A.

Jul 11, 2015Iron ores are usually found in the form of magnetite (Fe3O4), haematite (Fe2O3), goethite (FeO(OH), limonite (FeO(OH).n(H2O) and siderite.( FeCo3 ). Iron ore is the raw material used to make pig iron which is one of the main raw materials of steel. Ninety eight percent (98%) of the iron ore mined globally is used to make steel (, 2010).

Iron Mining In the Lake Superior Basin

The ore is crushed to approximately the size of a pea by rock crushers. It is then mixed with water and ground in rotating mills until it is as fine as powder. The iron is separated from the other minerals using magnets. The remaining material is called tailings and is dumped into tailings basins.

Hematite is the most important iron ore. The iron content of the pure minerals is as follows Ankerite is a carbonate of lime, magnesia, manganese, and iron. It is of valuable composition, carries only 14 or 15% of iron, and is used more for its lime and magnesia as a flux than for its iron content.

The ore grade, or concentration of an ore mineral or metal, as well as its form of occurrence, will directly affect the costs associated with mining the ore. The cost of extraction must thus be weighed against the metal value contained in the rock to determine what ore can be processed and what ore is of too low a grade to be worth mining.

Different Types of Iron Ore  Mineral Processing Metallurgy</h3>IMPURITIES IN IRON ORESIRON ORE FORMATIONORIGIN OF IRON ORE BODIESMAGNETITELIMONITESIDERITEThere are certain impurities that lower the value of iron ores or may even make them valueless. Sulphur in the ore goes partly into the iron and steel and makes them brittle. While it is possible by roasting the ore and by other means to remove the sulphur, the presence of any considerable amount is objectionable. Phosphorus in steel makes it brittle. For steel making the limit for phosphorus is one hundredth of one per cent for ten per cent of iron in the ore; this is the so called Bessemer

Iron ore Widespread occurrence of BIFs in the schist belts with grades seldom exceed 40% Fe. Purer iron ores are interbedded among basement gneisses in the Okene Lokoja area, which are probably older relics, perhaps correlated with the ores in Liberia and Guinea. 150 MT (approx.) of 30 50% Fe reserve have been proved in Itakpe hills.

Ore is a deposit in the Earths crust of one or more valuable minerals. The most valuable ore deposits contain metals crucial to industry and trade, like copper, gold, and iron. Copper ore is mined for a variety of industrial uses. Copper, an excellent conductor of electricity, is used as electrical wire.Copper is also used in construction.

Iron ore  </h3>OVERVIEWSOURCESMINE TAILINGSEXTRACTIONPRODUCTION AND CONSUMPTIONAVAILABLE IRON ORE RESOURCESIron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite, hematite, goethite, limonite or siderite. Ores containing very high quantities of hematite or magnetite are known as "natural ore" or "direct shipping ore", meaning they can be fed directly into iron making blast furnaces. Iron ore is the
