The function of potassium ethyl xanthate in froth floatation process is to make the ore

Options

  1. Awater repellant
  2. Blighter
  3. Cheavier
  4. Dattracted towards water

Correct answer

D. attracted towards water

Step-by-step solution

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.
