What is meant by froth stabilizers?

Explanation

### Step-by-Step Text Solution:

1. **Definition of Froth Stabilizers**: Froth stabilizers are substances used in the froth flotation method to maintain the stability of the froth that is formed during the separation process.

2. **Purpose of Froth Stabilizers**: The main purpose of froth stabilizers is to ensure that the froth remains stable for a longer period. This stability is crucial for effective separation of minerals from ores.

3. **Mechanism of Action**: When froth is formed during the flotation process, it can collapse or break down quickly without stabilizers. Froth stabilizers help to prevent this breakdown, allowing the froth to persist and facilitate the collection of valuable minerals.
