What is the role of Coke in the extraction of iron from

Actually the basic need of coke is to reduce the Iron oxide to Iron. However Coke is also used to make Carbon dioxide which can trap heat. Carbon dioxide is a greenhouse gas and so it is better at trapping and retaining the heat required for melti...

The Extraction of Iron Chemistry LibreTexts

This page looks at the use of the Blast Furnace in the extraction of iron from iron ore, and the conversion of the raw iron from the furnace into various kinds of steel. 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

Extraction of Iron Metallurgy Blast Furnace and Reactions

Carbon seems to play a significant role in influencing the brittleness and hardness balance in iron. To further reduce the carbon content of pig iron, it is melted again with scraps of iron and coke and subjected to the blast of hot air. This kind of iron is called Cast Iron and has a slightly lower carbon content 2 3 %. This is even harder than pig iron.

What is the role of coke in the extraction of iron from

The role of coke in the extraction of iron from its oxides is that it reduces the iron oxide to molten iron metal. Coke also when burnt in the blast furnace, supplies the heat required for carrying out the extraction of iron from its oxide.

what is the role of limestone in extraction of iron??

Iron is extracted from its ore, haematite, in a blast furnace. The ore is fed into the top of the furnace along with coke and limestone. The limestone decomposes in the hot furnace, forming calcium oxide. This reacts with the sandy impurities (silicon dioxide) to form a slag.
