Question

Froth floatation:

• A. Is a physical method of separating the mineral from the gangue
• B. Is a method of concentrating the ore based on the difference in wettability of the gangue and the ore
• C. Is applicable to sulphide ores
• D. Is a method in which impurities sink to the bottom.

Answer 1

Answer: (A), (B), (C), (D)

The correct options are
A Is a physical method of separating the mineral from the gangue
B Is a method of concentrating the ore based on the difference in wettability of the gangue and the ore
C Is applicable to sulphide ores
D Is a method in which impurities sink to the bottom.

Froth flotation is a method that is used to separate the sulphide ore from the impurity in the ore. It is based on the differential wetting of the ore by oil and the impurity by water.
