Iron Ore Charaterization And Origin Of

Iron ore - Wikipedia

Metallic iron is virtually unknown on the surface of the Earth except as iron-nickel alloys from meteorites and very rare forms of deep mantle xenoliths. Some iron meteorites are thought to have originated from accreted bodies 1,000 km in diameter or larger. The origin of iron can be ultimately traced to formation through nuclear fusion in stars and most of the iron is thought to have originated in dying stars that are large enough to collapse or explode as supernovae. Although iron is the fourth-most abundant element i…

Iron - Wikipedia

Iron is a chemical element with symbol Fe (from Latin: ferrum) and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is by mass the most common element on Earth, right in front of oxygen (32.1% and 30.1%, respectively), forming much of Earth's outer and inner core. It is the fourth most common element in the Earth's crust. In its metallic state, iron is rare in the Earth's crust, limited mainly to deposition by meteorites. Iron ores, …

Iron mining | Industrial History of Cumbria

The principal ore bodies occurred within the seven bands of the carboniferous limestone series, the latter having been subjected to varying degrees of earth movement and faulting, whilst the iron solutions penetrated the fault lines from above and below. The resultant ore bodies formed large flats (bodies of solid ore) which connected with the bedding planes of the host rock, irregular bodies ...
