Before iron ore can be used in a blast furnace, it must be extracted from the ground and partially refined to remove most of the impurities. Leaning on his long tongs, this young iron puddler's helper posed for this photograph in the early 1860s, when the Sons of Vulcan was a …
The production of iron or steel is a process consisting of two main stages. In the first stage pig iron is produced in a blast furnace. Alternatively, it may be directly reduced. In the second stage, pig iron is converted to wrought iron, steel, or cast iron.

Coke - mainly carbon The charge is placed a giant chimney called a blast furnace. The blast furnace is around 30 metres high and lined with fireproof bricks.
The process of extracting iron involves a number of steps. The first step to concentrate the iron ore and remove its contents of silica. To further remove any existing impurities, a complex process takes place in a blast furnace.

Production of iron from iron ore (hematite &… 90% of all mining of metallic ores is for the extraction of iron. Industrially, iron is produced starting from iron ores, principally hematite and magnetite by a carbothermic reaction (reduction with carbon) in a blast furnace at temperatures of about 2000 °C.
Iron is produced (extracted) in a blast furnace by reducing iron oxides with carbon and it is the carbon that removes the oxygen from the iron oxides – the carbon is known as the reducing agent. Coke is a cheap and readily made reducing agent.

Crude iron metal is produced in blast furnaces, where ore is reduced by coke to pig iron, which has a high carbon content. Further refinement with oxygen reduces the carbon content to the correct proportion to make steel.
Blast furnace: Blast furnace, a ... Blast furnaces produce pig iron from iron ore by the reducing action of carbon (supplied as coke) ... extraction and processing.
During the extraction of hematite(ore mining), very small sized iron particles are obtained . If particles of such sizes are directly used in the blast furnace for obtaining iron, they would choke the tuyeres and may even cause explosion inside th...
Extracting iron from iron ore using a Blast Furnace. The common ores of iron are both iron oxides, and these can be reduced to iron by heating them with carbon in the form of coke. Coke is produced by heating coal in the absence of air. Coke is cheap and provides both the reducing agent for the reaction and also the heat source.
