Extracting iron from iron ore . In the 12th century, men started to mine iron ore from rock. They learnt how to recognize rock that contained iron ore and broke off pieces of rock by lighting fires against it, to make it brittle. The work was done from the surface down, excavating the rock in opencast mines and following the veins of ore.

The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron(III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes known as tuyeres.

Iron Mining Process. From blasting to crushing to separation – more than 85% of the iron mined in the United States is mined in northeastern Minnesota to make our nation’s steel. Blasting Taconite is a very hard rock. Using explosives, the taconite is blasted into small pieces. ... The iron ore

Mining and processing of iron ore involves coarse crushing and screening. Iron ore is beneficiated by crushing and then separating the iron from the gangue minerals through screening. This is usually so efficient that lower grade ore can be treated especially when the magnetite is quite coarse.

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.

Read MoreMar 26, 2020 Iron 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.

Ore Mountain, a mile west of the furnace, was the source of the iron ore that was refined to pig iron. Mining was relatively easy because a four foot deep layer of raw ore lay just below the surface. Workers needed only to clear away trees and topsoil to reach the ore , the ore was ready for the furnace. Iron
