Question

During the concentration of sulphide ores via the froth flotation process, various specialized reagents are added. Which of the following correctly describes the role of these specific reagents?

Answer: A,B,D

💡 Solution & Explanation

Aniline and cresols are froth stabilizers, not depressants. Pine oil forms the froth, xanthates act as collectors to make ore water-repellent, and $NaCN$ depresses $ZnS$ by forming $Na_2[Zn(CN)_4]$.
