Aluminium is extracted using electrolysis because it has a high melting point, making it more energy efficient to use electrolysis rather than the blast furnace. The electrolysis process involves passing an electric current through a molten aluminum oxide mixture, which separates the aluminum from the oxygen.

Why sodium cannot be extracted by the blast furnace?
Sodium cannot be extracted by the blast furnace because it is a highly reactive metal that forms stable compounds with oxygen. This makes it energetically unfavorable to extract sodium through reduction reactions in a high temperature blast furnace. Instead, electrolysis is typically used to extract sodium from its compounds like sodium chloride.
Why zinc cannot be extracted in blast furnace?
Zinc has a lower boiling point than iron, so it vaporizes and escapes as a gas in the high temperatures of a blast furnace. This makes it challenging to extract zinc using traditional blast furnace methods, as it does not accumulate as a molten metal like iron. Instead, zinc is typically extracted using electrolysis or through a distillation process.
Why can't aluminium be extracted from aluminium ore using a blast furnace?
Because it is more reactive then carbon to be extracted in a blast furnace. Remember carbon is the reducing agent and for it to work the metal being extracted has to be lower in the reactivity series, e.g. iron
How is aluminium extracted?
Aluminium is extracted from its ore, bauxite, using the Bayer process. This involves crushing the bauxite, dissolving it in hot sodium hydroxide solution to form aluminate solution, then cooling and filtering it to separate out impurities. The alumina is then electrolyzed to produce aluminium metal.
Why is iron extracted using blast furnace and not by thermit reaction?
Iron is typically extracted using a blast furnace because it allows for large-scale production of iron with high efficiency. The thermite reaction is not as practical for large-scale production as it involves a smaller scale reaction and can be difficult to control. Additionally, the blast furnace method allows for the extraction of impurities from the iron ore.

What industrial plant is iron extracted from?
Iron is primarily extracted from iron ore in a blast furnace at an iron and steel plant. The iron ore is first processed into iron oxide, which is then reduced to metallic iron using carbon as a reducing agent in the blast furnace.

Why is electrolysis much more expensive than using a blast furnace?
Electrolysis involves passing an electric current through a molten mixture, which requires large amounts of electricity and specialized equipment, making it more expensive. In contrast, a blast furnace uses chemical reactions and high temperatures to separate metals from their ores, which may be more cost-effective depending on the specific application and material being processed.
Is iron oxide ruduced or oxidised in a blast furnace?
Iron oxide is reduced in a blast furnace. This process involves the removal of oxygen from iron oxide to produce elemental iron.
What is the German word for blast furnace?
Blast furnace = Hochofen
What is Blast Furnace?
A blast furnace is used to extract iron from its ore.
Is sodium cheap?
Even though the ores of both the metals is quite cheap, Sodium has to be extracted through electrolysis which is quite an expensive process where as Iron is extracted from Blast furnace which is comparatively cheaper to run.
