Options

A. coconut oil
B. cartor oil
C. plamitic oil
D. pine oil.

Answer

To solve the question regarding the oil used as a frothing agent in the froth-floatation process, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Froth-Floatation Process**:
- The froth-floatation process is a method used for the separation of minerals from their ores. It involves the use of a frothing agent to create a froth that selectively separates the desired mineral from the gangue.

2. **Identify the Options**:
- The options given are:
- Coconut oil
- Carter oil
- Palmitic oil
- Pine oil

3. **Evaluate the Properties of Each Oil**:
- **Coconut Oil**: Generally used in cooking and cosmetics, it does not have specific properties that enhance the froth-floatation process.
- **Carter Oil**: This is not commonly recognized in the context of froth-floatation.
- **Palmitic Oil**: A saturated fatty acid, not typically used as a frothing agent.
- **Pine Oil**: Known for its low affinity for water, which helps in increasing the hydrophobicity of the minerals.

4. **Determine the Correct Answer**:
- Among the options, **Pine Oil** is the correct choice. Its properties allow it to effectively create a froth that helps in the separation of minerals from ores in the froth-floatation process.

5. **Conclusion**:
- Therefore, the oil used as a frothing agent in the froth-floatation process is **Pine Oil**.

### Final Answer:
**Pine Oil**
