The problems that iron impurities can cause in a blast furnace can include the iron not melting down correctly, obnoxious fumes being created, and the impurities could ruin an entire batch of melted iron.

∙ 11y agoNinety percent of all mining of metallic ores is for the extraction of iron. Industrially, iron production involves iron ores, principally hematite (nominally Fe2O3) and magnetite (Fe3O4) in a carbothermic reaction (reduction with carbon) in a blast furnace at temperatures of about 2000 °C. In a blast furnace, iron ore, carbon in the form of coke, and a flux such as limestone (which is used to remove silicon dioxide impurities in the ore which would otherwise clog the furnace with solid material) are fed into the top of the furnace, while a massive blast of heated air, about 4 tons per ton of iron, is forced into the furnace at the bottom.
In the furnace, the coke reacts with oxygen in the air blast to produce carbon monoxide:
2 C + O2 → 2 CO
The carbon monoxide reduces the iron ore (in the chemical equation below, hematite) to molten iron, becoming carbon dioxide in the process:Fe2O3 + 3 CO → 2 Fe + 3 CO2
Ansewr: Heat and CO2 Carbon dioxide

What happens to the melting and boiling point of a substance if it contains impurity?
If the impurity has a higher boiling point then the boiling point of the mixture will also be slightly higher, and vice versa.
What happened when impurity is added in phenol water system?
the critical solution temperature for phenol water system increases
How is chitosan extraction from shelfish?

Does iron have definite shape and a definite volume?
When iron is a liquid, it does not. Solid iron, however, does.
What types of iron is there?
pig iron, wrought iron and cast iron. These are broad classifications used commercially, they can be subclassified. Chemically we say that its pure or impure, contains sulphur/phosphorous/impurities(slag, etc.)/carbon in so and so % range
When is electrolysis used for extraction?
for extraction of iron
What is liberation in mineral extraction?
liberation itself refers to liberate , the process of separation of the metal and impurity from the compound of mineral is called liberation in mineral extraction
Why is there an Iron chloride impurity in chromatography experiment?
The water used to dilute HCL may contain Iron chloride as an impurity so the solution you prepare as a mobile phase is contaminated with iron chloride.
How are amethyst and quatz different?
