Under Ground Mining Of Iron Ore

Roughly 98% of iron ore on the global market is used in iron and steel production. Mining and processing. Common methods of extracting the iron ore consist of blasting, drilling, or general excavating, Most iron ore is produced from open-pit mines. After the iron ore is out of the ground, it may be shipped to the iron and steel manufacturing plant.

Shaft Mining. Shaft mining is a form of underground mining where shafts are pushed vertically from top to bottom to excavate the ores and minerals. It is also called shaft sinking. It is best suited for concentrated minerals such as iron, coal, etc. which can be found at the depth of the earth's surface. It is found mostly all over the world.
