Question

The ______________ method is based on the two opposite properties, hydrophilic and hydrophobic, of

the particles

a) Magnetic separation b) Hydraulic c) Froth floatation d) Wilfley table​

Answer 1

Answer:

The Froth floatation method  is based on the two opposite properties, hydrophilic and hydrophobic, of  the particles.

• froth floatation method is used as application of adsorption.

• a low grade sulphide ore is concentrated by  sperating it from silica and other earthy matter.

• the agent used in this method are pine oil and frothing agent.

• the material which has hydrophobic properties then only can get attracted toward froth and not with water

• so , the option C is correct answer.
