Levigation is generally employed for concentration of sulphide ores.

Explanation

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

1. **Understanding Levigation**: Levigation is a process used for the separation of fine particles of solids based on their relative densities. It is primarily employed for the concentration of ore, particularly oxide ores.

2. **Identifying the Type of Ore**: The question states that levigation is used for the concentration of sulphide ores. It is essential to recognize the difference between oxide ores and sulphide ores.

3. **Correct Process for Sulphide Ores**: The concentration of sulphide ores is typically achieved through a different method known as froth flotation. This method exploits the differences in the hydrophobicity of the minerals.

4. **Conclusion**: Since levigation is not used for the concentration of sulphide ores but rather for oxide ores, the statement in the question is false.

5. **Final Answer**: Therefore, the statement "Levigation is generally employed for concentration of sulphide ores" is **False**.
