What is the role of lime or limestone in the extraction of Iron…
The lime thus formed reacts with the Silicate present in the ore of Iron which is Silicon oxide. The chemical reaction occurs as follows: CaO s (Lime) + SiO 2 s (Silicates) → CaSiO 3 l Calcium silicate (Slag) Thus, limestone can be used to remove unwanted impurities from the ore of Iron during extraction.

Extraction of Iron from Haematite (iron ore) in the Blast …
Carbon monoxide is reducing agent, so causes the reaction by removing the oxygen. Iron sinks to the bottom of the blast furnace as a liquid due to the high temperatures. This is a redox reaction as both oxidation and reduction occur in the same reaction. (Loss of oxygen - reduction -> iron oxide is reduced.
