Smelting is termed to the proces in which

Options

A. The ore is heated in the absence of air
B. Ore is cold
C. The ore is heated in the presence of air
D. Ore is melted

Answer

**Step-by-Step Solution:**

1. **Definition of Smelting**: Smelting is a metallurgical process used to extract metals from their ores by heating and melting. This process typically involves the use of heat and a reducing agent.

2. **Heating Ores**: In smelting, ores containing metals (like copper, iron, etc.) are heated to a temperature that is above the melting point of the metal. This allows the metal to separate from the ore.

3. **Role of Oxygen**: Oxygen is often introduced during the smelting process to facilitate oxidation reactions. This helps in the removal of impurities from the metal.

4. **Use of Coke**: Coke, a form of carbon, is commonly used as a reducing agent in smelting. It helps in the reduction of metal oxides back to their metallic form.

5. **Final Product**: The end result of the smelting process is the extraction of pure metal from its ore, which can then be further processed or used in various applications.

**Conclusion**: Smelting is a process that involves heating ores of various metals in the presence of oxygen and coke to extract the metal.
