Froth floatation process is used for the concentration of which ore?

Options

A. Sulphide
B. Oxide
C. Carbonate
D. Chloride

Explanation

**Step-by-Step Solution:**

1. **Understanding Froth Flotation Process**:
- Froth flotation is a method used to separate valuable minerals from their ores. It is particularly effective for the concentration of certain types of ores.

2. **Identifying the Type of Ore**:
- The question asks about the specific type of ore that is concentrated using the froth flotation process. The options provided are:
- Sulphide ore
- Oxide ore
- Carbonate ore
- Chloride ore

3. **Characteristics of Froth Flotation**:
- Froth flotation is primarily used for the concentration of sulphide ores. This process involves removing gangue (unwanted materials) from the ore, which is essential for obtaining the desired minerals.

4. **Process Overview**:
- The froth flotation process involves several steps:
- **Suspension Creation**: A suspension of powdered ore is made with water.
- **Addition of Collectors and Stabilizers**: Collectors (like fatty acids and xanthates) enhance the non-wettability of mineral particles, while stabilizers (like aniline) help stabilize the froth.
- **Wetting**: Mineral particles are wetted by oil, and gangue particles are wetted by water.
- **Agitation**: The mixture is agitated, which introduces air and forms froth.
- **Recovery**: The froth, which is rich in mineral particles, is dried, and the minerals are recovered.

5. **Conclusion**:
- Based on the characteristics and the process of froth flotation, it is concluded that the froth flotation process is specifically used for the concentration of **sulphide ore**.

**Final Answer**: Froth flotation process is used for the concentration of **sulphide ore**.
