Question
In the froth flotation process for concentrating sulphide ores, which of the following accurately describes the precise chemical role and structural mechanism of sodium ethyl xanthate?
Answer: D
💡 Solution & Explanation
Collectors like sodium ethyl xanthate increase the non-wettability of the mineral particles. The polar group attaches to the sulphide ore, and the non-polar alkyl chain faces outward, making the particle water-repellent (hydrophobic) so it floats with the air bubbles.
