Iron Ore

Iron ore is the primary raw material used to make steel. Steel is strong, long-lasting and cost-efficient making it perfect for everything from washing machines to cars, bridges and skyscrapers. Iron ore rock. A key objective in the metallurgical treatment of any ore is the separation of ore minerals from gangue minerals within the rock.Iron ore is the primary raw material used to make steel. Steel is strong, long-lasting and cost-efficient making it perfect for everything from washing machines to cars, bridges and skyscrapers. Iron ore rock. A key objective in the metallurgical treatment of any ore is the separation of ore minerals from gangue minerals within the rock.Iron Ore is a chemical sedimentary rock that forms when iron and oxygen and sometimes other substances combine in solution and deposit as a sediment. Hematite shown above is the most common sedimentary iron ore mineral. The specimen shown above is about two inches five centimeters across.Goethite is an iron oxide hydroxide, although manganese can substitute for up to 5 percent of the iron. It forms as a weathering product in the oxidation zones of veins of iron minerals, such as pyrite, magnetite and siderite. Goethite may occur with these minerals in the gossan, or iron hat, which is the weathered capping of an iron ore deposit.The character of the rock which the vein traverses is often variable, for the gold-bearing veins appear in either igneous or sedimentary rocks, sometimes at the contact zone between igneous and sedimentary rocks, little influenced by the character of the rock which

Iron-bearing rock may be upgraded by removing gangue through concentration.Though taconite was identified as an iron-bearing rock on the Iron Ranges of northern Minnesota long before the 1950s, it wasnt until then that it was profitably extracted, processed, and shipped to steel mills on the Great Lakes. As natural ore reserves were diminished, taconite became an alternative source of iron that allowed the Iron Range to continue mining operations in a changing ...

In that year iron-bearing rocks with some asso- ciated ore were encountered in drilling operations south of Deerwood, and in 1905 ore was also found north of Deerwood, near Babbit Lake. After these discoveries exploration and drilling were carried on withThese rock types are currently considered to be relatively insignificant as an iron ore resource in South Australia. Iron-bearing igneous rocks are known to occur within the Giles Complex of the Musgrave Block as small, yet rich segregations. Magnetite-ilmenite segregations have been reported in drill holes within the Malbooma Anorthosite Complex.

Iron ore is hosted in the Lower-Middle part of the rock system.What is Iron Ore Earths most important iron ore deposits are found in sedimentary rocks. They formed from chemical reactions that combined iron and oxygen in marine and fresh waters. The two most important minerals in these deposits are iron oxides hematite Fe 2 O 3 and magnetite Fe 3 O 4. These iron ores have been mined to produce almost every iron and steel object that we use today -The most important iron-bearing minerals in iron formations are hematite, magnetite, and greenalite. These deposits constitute the worlds major source of iron ore . Classic examples are found in the Mesabi Range of Minnesota, U.S., and the Kiruna ores of Sweden.
