- Fatty acids
- Pine oil
- Cresol
- Xanthates
The Correct Option is C
Solution and Explanation
The correct option is (C): Cresol
Creson and aniline are used as stabilizers.
Pine oil, fatty acid, and xanthates are used as collectors.

What are Ores and Minerals?
Minerals are the naturally occurring, homogeneous inorganic solid substances. They are having a definite chemical composition and crystalline structure, hardness and color. For example, copper pyrite, calamine, etc.
Impurities in an ore are called gauge. The removal of a gauge from the ore is called concentration ore.
Several steps are involved in the extraction of pure metal from ores. Major steps are as follows –
- Concentration of the ore
- Isolation of the metal from its concentrated ore
- Purification of the metal
