The method used to extract metals from the ore in which they are found depends on their reactivity. For example, reactive metals such as aluminium are extracted by electrolysis, while a less-reactive metal such as iron may be extracted by reduction with carbon or carbon monoxide.

Metal is obtained from metal oxide through a process called reduction. Reduction is a chemical reaction in which electrons are added to a substance, causing a decrease in oxidation state. This process is commonly used to extract metals from their oxides.
Steps Involved in Obtaining Metal from Metal Oxide
1. Heating the metal oxide: The metal oxide is heated at a high temperature. This is done to provide sufficient energy for the reduction process to occur. The heating process is also known as calcination.
2. Addition of reducing agent: A reducing agent is added to the metal oxide. The reducing agent is a substance that donates electrons to the metal oxide, causing it to be reduced. The most common reducing agent used is carbon. When carbon is heated with metal oxide, it reacts with the oxygen in the metal oxide to form carbon dioxide, leaving behind the metal.
3. Separation of metal: The metal obtained from the reduction process is separated from the remaining material. This can be done through various methods based on the physical and chemical properties of the metal. For example, in the case of iron, the metal can be separated from the remaining material using a magnet.
Conclusion
The process of obtaining metal from metal oxide through reduction is an important industrial process. This process is used to extract metals such as iron, copper, and zinc from their respective oxides. The process involves heating the metal oxide and adding a reducing agent, such as carbon, to the mixture. The metal is then separated from the remaining material using various methods.
