What are the collectors used in froth floatation process? Name a substance that can be used as such.

Explanation

**Step-by-Step Solution:**

1. **Understanding the Froth Flotation Process:**
- The froth flotation process is a method used for the separation of hydrophobic materials from hydrophilic ones, primarily in the mining industry. It is commonly used for the concentration of sulfide ores.

2. **Role of Collectors:**
- In the froth flotation process, collectors are chemical reagents that enhance the hydrophobicity of the mineral particles. This means they help the particles to repel water, allowing them to attach to air bubbles and rise to the surface, forming a froth.
