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

Options

  1. APine oils
  2. BFatty acids
  3. CXanthates
  4. DCresols

Correct answer

D. Cresols

Step-by-step 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.
