Air introduced near the bottom of a flotation cell containing pulped ore forms
coursing bubbles, which rise through the liquid and emerge as mineralized
bubbles forming a semistable froth column. This depends for its continuity
partly on the surface-active reagents borne by the mineral in the air-water
interphase of each bubble and partly on the aid of frothing reagents. Pryor, 1
