What is the process of smelting ? Give one suitable example also.

Explanation

**Step-by-Step Solution:**

1. **Definition of Smelting**: Smelting is a metallurgical process used to extract metals from their ores by heating the metal oxide to a high temperature in the presence of a reducing agent, typically carbon.

2. **Chemical Reaction**: During smelting, the carbon in the fuel reacts with the oxygen in the metal oxide. This reaction reduces the metal oxide to its elemental form while producing carbon monoxide (CO) or carbon dioxide (CO₂) as by-products.

3. **Formation of Pure Metals**: As a result of the reduction reaction, pure metals are obtained from their ores. The high temperature facilitates the breaking of the bonds in the metal oxide, allowing the metal to be liberated.
