Question

Froth floatation process is used for the concentration of sulphide ores. This is an illustration of the practical application of:

• A. Adsorption
• B. Absorption
• C. Sedimentation
• D. Coagulation

Answer 1

The correct option is A Adsorption

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in several processing industries. It has been described as the single most important operation used for the recovery and upgrading of sulfide ores.

Froth floatation process is used for the concentration of sulphide ores. This is an illustration of the practical application of adsorption, as the sulphide ores get preferentially adsorbed over the impurities.

Hence, the correct option is $\text{A}$
