Froth flotation

A

is a physical method of separating mineral from the gangue

B

is a method to concentrate the ore depending on the difference in wetability of gange and there

C

is used for the sulphide ores

D

is a method in which impurities sink to the bottom

Text Solution

Verified by Experts

The correct Answer is:
A, B, C, D
This is used to concentrate sulphide ores it is a physical method of separation of mineral from impurity. It is depends on difference in wetability of gangue and ore particles, ore particles wetted by oil and gangue particles wetted by water and settle at bottom.
