Sulphide ore of copper can be concentrated by

Options

A. (A)Forth flotation process
B. (B)electromagnetic process
C. (C)gravity separation
D. (D)distillation

Answer

To solve the question "Sulphide ore of copper can be concentrated by?", we will analyze the options given and determine the correct method for concentrating copper sulphide ore.

### Step-by-Step Solution:

1. **Understanding Concentration of Ore**:
- Concentration of ore refers to the process of removing impurities and increasing the percentage of the desired metal in the ore. This is also known as ore beneficiation.

2. **Analyzing the Options**:
- **Option A: Froth Flotation Process**: This method is widely used for concentrating sulphide ores. It involves adding chemicals (like pine oil) that selectively wet the sulphide minerals, allowing them to float to the surface and be collected as froth.
- **Option B: Electromagnetic Process**: This method requires the ore to be magnetic. Since copper and its sulphide ores are not magnetic, this method is not applicable.
- **Option C: Gravity Separation**: This method relies on the difference in density between the ore and the gangue. However, the densities of copper sulphide and its gangue are similar, making this method ineffective.
- **Option D: Distillation**: This method is typically used for separating components based on differences in boiling points, which is not applicable for solid ores like copper sulphide.

3. **Conclusion**:
- Based on the analysis, the most suitable method for concentrating copper sulphide ore is the **Froth Flotation Process** (Option A).

### Final Answer:
The sulphide ore of copper can be concentrated by **Froth Flotation Process**.
