Description: Which of the following is used as a stabilizer during the concentration of sulphide ores?

Solution

In froth floatation process for concentration of sulphide ores:

- Collectors (like pine oils, fatty acids, xanthates) enhance the non-wettability of the mineral particles.

- Frothers help in forming a stable froth.

- Stabilizers stabilize the froth. Cresols are used as stabilizers.

Pine oils and xanthates are collectors, not stabilizers.

The correct answer is Option 4: Cresols.
