What is the role of adsorption in froth floatation process used especially for concentration of sulphide ores?

Explanation

### Step-by-Step Solution:

1. **Understanding Froth Flotation Process**:
The froth flotation process is a method used to separate hydrophobic materials from hydrophilic ones, particularly in the concentration of sulphide ores.

2. **Role of Adsorption**:
In this process, the key role of adsorption is to allow the ore particles (sulphide ores) to attach to the bubbles formed in the froth. This is essential for the separation of valuable minerals from the gangue (waste material).
