Pig iron - Wikipedia

Pig iron is an intermediate product of the iron industry in the production of steel, also known as crude iron, which is obtained by smelting iron ore in a blast furnace. Pig iron has a very high carbon content, typically 3.8-4.7%, along with silica and other constituents of dross...

Iron ore is used to make iron and steel eg haematite and magnetite. 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.

Blast Furnace - an overview | ScienceDirect Topics

The main outputs of blast furnaces includes pig iron and slag, which is formed by combination of limestone with sulfur and other impurities. Pig iron is typically tapped every 3 to 5 hours in quantities of 300 to 600 tons. After tapping, the pig iron is transported, typically in liquid form, to steel-making operations.

Iron Ore and Coke Form Pig Iron in the Blast Furnace. To create pig iron in the blast furnace we need iron ore and coke. Iron ore may contain contaminants that must be removed by adding flux. The mixture of iron ore, flux and sometimes scrap metal is called a burden. A typical blast furnace is a cylindrical shaft furnace with a refractory ...

Creating Iron | HowStuffWorks

Liquid iron collects at the bottom of the blast furnace, underneath a layer of slag. The blacksmith periodically lets the liquid iron flow out and cool. At this point, the liquid iron typically flows through a channel and into a bed of sand. Once it cools, this metal is known as pig iron. To create a ton of pig iron, you start with 2 tons (1.8 ...

"During extraction of iron another impurity appear which is carbon from coke in furnace." However, I don't understand how there will be enough unreacted carbon that would blend with iron. As reaction of carbon and oxygen is very exothermic so there must be enough energy for all carbon atoms to react with oxygen.
