Frother is added in the froth floatation cell used in ore beneficiation to stabilise the air bubbles (i.e., froth), which will hold the ore particles, but it does not affect the floatability of minerals. Which of the following is not used as a frother ?
Correct answer: B. Xanthaies
- A. Cresylic acid
- B. Xanthaies
- C. Pine oil
- D. All A, B. & C.
Explanation
Pine oil and cresylic acid are common frothers that stabilise the froth. Xanthates are mainly collectors that selectively render mineral particles hydrophobic, so they are not frothers.
