Q12 / 90 · JEE Main 2023 (10 Apr Shift 1) · Chemistry

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

  • A
    Pine oils
  • B
    Fatty acids
  • C
    Xanthates
  • Correct answer
    D
    Cresols

Solution

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. The principle of froth flotation process is that sulphide ores are preferentially wetted by the pine oil, whereas the gangue particles are wetted by the water. Cresols and aniline are used as froth stabilisers.

Hence, the correct answer is option: 'D'.
