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
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.
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.
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.
Copper is less reactive than sodium but cannot be extracted by heating with carbon in a furnace due to its position in the reactivity series. Instead, copper is typically extracted using electrolysis or by reduction with more reactive metals such as iron.
Aluminum is extracted from bauxite, the ore in which aluminum oxide is found, through a refining process known as the Bayer process. The bauxite is mixed sodium hydroxide and heated, which separates the aluminum oxide because it dissolves in the sodium hydroxide while the rest of the bauxite does not.

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.

That iron is too brittle.
Aluminium is not extracted from alumina by pyrometallurgical operations because the melting point of alumina is very high (over 2000°C), making it energetically intensive and expensive to extract aluminium through traditional pyrometallurgical methods. Instead, aluminium is typically extracted from alumina using the Hall-Héroult process, which involves electrolysis at a much lower temperature.

First: Roast the Galena in a blast furnace for 30 minuets. Second: Add Carbon to the blast furnace to remove impurities. Third: Tag off your lead from the bottom of the blast furnace.
The exothermic reaction that causes the temperature to rise in the blast furnace during the reduction of hematite using coke is the combustion of carbon (C) in coke with oxygen (O2) to produce carbon dioxide (CO2) and release heat energy. This reaction helps maintain the high temperatures necessary for the reduction of hematite to iron.
Some will give credit to Sir Henry Bessemer invented the modern day blast furnace in 1855. However, if you look historically the Chinese invented the blast furnace. By at least the 4th century the Chinese have developed blast furnaces to obtain cast iron from iron ore. This was 1200 years before the first blast furnace showed up in Europe.
