General Principles and processes of Isolation of Elements
easy
During initial treatment, preferential wetting of ore by oil and gangue by water takes place in
A
Levigation (gravity separation)
B
Froth floatation
C
Leaching
D
Bessemerisation
Solution
Principle involved in the froth floatation method is the difference in the wetting properties of the ore and the gangue particles. The sulphide ore particles are preferentially wetted by oil while gangue particles are preferentially wetted by water.
