In the froth floatation process the collectors such as pine oils and xanthates etc. enhance

Options

A. Non-wettability of the mineral particles in froth
B. Non-wettability of the mineral particles in water
C. Non-wettability of the gangue particles in froth.
D. Non-wettability of the gangue particles in water

Answer

### Step-by-Step Solution:

1. **Understanding Froth Flotation Process**:
- The froth flotation process is primarily used for the separation of minerals from their ores, particularly for sulfide ores. It involves creating a suspension of powdered ore in water.

2. **Role of Collectors**:
- Collectors such as pine oil and xanthates are added to the suspension. Their main function is to increase the non-wettability of mineral particles.

3. **Non-Wettability Explained**:
- Non-wettability refers to the property of a surface that does not allow water to spread on it. In the context of froth flotation, this means that the mineral particles will not adhere to water, allowing them to attach to air bubbles instead.

4. **Distinguishing Between Mineral and Gangue Particles**:
- It’s important to differentiate between mineral particles (the desired material) and gangue particles (the impurities). Collectors enhance the non-wettability of the mineral particles, making them more likely to float.

5. **Analyzing the Options**:
- The question provides several options regarding what the collectors enhance. The correct option must reflect that collectors enhance the non-wettability of mineral particles in water.

6. **Final Selection**:
- After analyzing the options, the correct answer is that collectors enhance the non-wettability of mineral particles in water.

### Final Answer:
In the froth flotation process, the collectors such as pine oil and xanthates enhance the non-wettability of the mineral particles in water.
