Question

Which of the following
processes of metallurgy
involves adsorption.
A)Magnetic separation method
B)Electrostatic separation
method
C)Gravity separation method

D)Froth flotation process

Answer 1

Froth flotation is a process of metallurgy and it involves adsorption.

What is the froth flotation process?

• The Froth floatation process is a physicochemical technique and is used to differentiate the particles on the basis of their surface wettability.
• This process takes place by the suspension of particles in an aqueous solution.
• In the Froth flotation process, the mixture of sulfide ore, water, and pine oil is shaken together.
• On one hand, the particles of sulfide ore are adsorbed on froth that floats.
• On the other hand, the pine oil and water settle down in the tank.

So, the correct answer is (D) the Froth flotation process.
