Answer

**Step-by-Step Text Solution:**

1. **Understanding the Terms:**
- **Ore:** An ore is a naturally occurring solid material from which a metal or valuable mineral can be extracted profitably. It is often a mixture of minerals and metals.
- **Gangue:** Gangue refers to the impurities or non-valuable materials that are found mixed with the ore.

2. **Identifying the Process:**
- The process of removing gangue from ore is essential for obtaining pure metals. This process is crucial in metallurgy and is often referred to as "concentration of ores."

3. **Methods of Concentration:**
- There are various methods to concentrate ores and remove gangue, including:
- **Hydraulic Washing:** A method that uses water to separate lighter gangue particles from heavier ore particles.
- **Froth Flotation:** A process that uses differences in the hydrophobicity of minerals to separate them from gangue.

4. **Conclusion:**
- The process of removal of gangue from ore is known as **concentration of ores**.
