Mining of Iron Ores – IspatGuru

Mar 14, 2014The most predominant surface mining methods used for mining of iron ores are open pit mining methods and open cut mining methods. However a few underground iron ore mines are also in operation around the globe. The decision for employing surface mining or underground mining is dependent on the proximity of the ore body to the surface. Open pit and

Digging deeper: Mining methods explained

Large scale mechanised mining methods we use include: long-wall mining, where a long wall of coal is mined in a single slice, usually by a large machine. sub-level-caving, where levels of the ore are blasted by explosives; and ; block caving, where large areas of the ore body are blasted and then extracted with the assistance of gravity.

Iron Ore Mining

MINING AND PROCESSING: Iron ore mining can be broadly divided into two categories namely 1) manual mining which is employed in small mines and 2) mechanized mining is suitable for large iron ore mines. Manual mining method is normally limited to float ores and small mines. Mining of reef ore is also being done manually on a small scale.

Impervious shales form the bottom of the ore bodies. Many of these ore bodies do not extend to the surface and thus the iron-formations are sufficiently deformed so that it was necessary to utilize underground mining methods rather than the large open-pit operations as on the Mesabi (Minnesota) Range.

How Is Iron Extracted From the Earth?

Mar 26, 2020Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore.
