Question
Which of the following is used as a stabilizer during the concentration of sulphide ores? (A) Pine oils (B) Xanthates (C) Fatty acids (D) Cresols
Answer: D
💡 Solution & Explanation
In Froth floatation process, a suspension of the powdered ore is made with water. To it, collectors and froth stabilisers are added. Collectors (e. g. xanthates, etc.) enhance non-wettability of the mineral particles and froth stabilisers (e. g., cresols, aniline) stabilise the froth.
