What is pyrometallurgy ? Explain with one example.

Explanation

**Step-by-Step Solution:**

1. **Definition of Pyrometallurgy:**
Pyrometallurgy is a branch of metallurgy that involves the extraction of metals from their ores through the application of heat. This process typically involves the reduction of metal oxides by heating them with a reducing agent.

2. **Process Overview:**
In pyrometallurgy, metal oxides are heated to high temperatures, often in the presence of carbon or other reducing agents. The heat causes the metal oxide to lose oxygen, resulting in the formation of pure metal and gaseous byproducts.
