The function of potassium ethyl xanthate in froth floatation process is to make the ore
- A water repellant
- B lighter
- C heavier
- D attracted towards water
Answer & Solution
Correct Answer
(D) attracted towards water
Step-by-step Solution
Detailed explanation
In froth floatation process, potassium ethyl xanthate acts as collectors. It attaches itself by polar group to grain of minerals and pass into water froth. It increases the non-wettability of the mineral particles.
