How to Improved Fine Particle & Bubble Flotation
The pulp was diluted to 25 pct solids with clear saturated lime water, and Dowfroth 100 frother was added to raise the frother concentration to 25 ppm (0.075 g/kg). The sample was floated for 5 min at 1,000 r/min with 1.5 L/min of air. Saturated lime water was used to maintain the pH and the froth height.
