Cresols and aniline are used as .............. in froth floatation process:

Answer

**Step-by-Step Solution:**

1. **Understanding Froth Flotation Process**: The froth flotation process is a method used for the separation of hydrophobic materials from hydrophilic ones. It is commonly used in the extraction of metal ores, particularly sulfide ores.

2. **Role of Cresols and Aniline**: Cresols and aniline are organic compounds that serve as collectors in the froth flotation process. Collectors are substances that increase the hydrophobicity of the mineral particles, allowing them to attach to air bubbles and rise to the surface.

3. **Hydrophobic vs. Hydrophilic**: In the context of froth flotation, hydrophobic materials are those that do not mix with water and can be separated from hydrophilic materials, which do mix with water. The goal is to selectively separate valuable minerals from the ore.

4. **Function of Collectors**: Cresols and aniline act as stabilizers in the froth flotation process. They help in the formation of the froth by ensuring that the mineral particles remain non-wettable (hydrophobic). This non-wettability is crucial for the effective separation of minerals.

5. **Conclusion**: Therefore, in the froth flotation process, cresols and aniline are used as collectors or stabilizers to enhance the separation of hydrophobic mineral particles from hydrophilic ones.

**Final Answer**: Cresols and aniline are used as collectors in the froth flotation process.
