      In froth floatation process, advantage is taken of prefferential wetting of ore particles by oil and gangue particles by water. Pine oil or eucalyptus oil has tendency to wet metal sulphides. Thus sulphide ore is present in oily froth whereas gangue particles settle at the bottom,and hence fuller concentration is achieved.
