In the froth-floatation process, the ore particles float because
A.they are light
B.their surface is not easily wetted by water✓ Correct
C.they bear electrostatic charge
D.they are insoluble
Explanation
In froth-floatation process, sulphide ores are concentrated since their surface are not wetted with water and come at top of solution with froth.
