The production of iron from its ore involves an oxidation-reduction reaction carried out in a blast furnace. Iron ore is usually a mixture of iron and vast quantities of impurities such as sand and clay referred to as gangue.Iron, atomic number 26, is the most abundant element on earth by mass. It belongs to the 3d series or first transition series of the periodic table. Pure metallic iron is not usually found in the earth’s crust. Therefore, extracting metal from ore is the only way to obtain usable iron. Extraction of iron from its ore is a lengthy process andNEET UG : Extraction of Iron, chemistry by unacademy

The production of iron from its ore involves an oxidation-reduction reaction carried out in a blast furnace. Iron ore is usually a mixture of iron and vast quantities of impurities such as sand and clay referred to as gangue. The iron found in iron ores are found in the form of iron oxides. As a result of these impurities, iron must be firstThe iron in the chalcopyrite ends up converted into an iron(II) silicate slag which is removed. Most of the sulfur in the chalcopyrite turns into sulfur dioxide gas. This is used to make sulfuric acid via the Contact Process. An overall equation for this series of steps is: \[2CuFeS_2 + 2SiO_2 +4O_2 \rightarrow Cu_2S + 2FeSiO_3 + 3SO_2 \label{1} \]4.1.6.2: The Extraction of Copper Chemistry LibreTexts

Aluminium Metallurgy Chemistry LibreTexts
Introduction. Aluminum is too high in the electrochemical series (reactivity series) to extract it from its ore using carbon reduction. The temperatures needed are too high to be economic. Instead, it is extracted by electrolysis. The ore is first converted into pure aluminum oxide by the Bayer Process, and this is then electrolyzed in solution in molten cryolite another Iron is extracted in a large container called a blast furnace from its ore, haematite Modern blast furnaces produce approximately 10000 tonnes of iron per day The process is demonstrated and explained below: Diagram showing the carbon extraction of iron.
