Abstract
The U.S. Bureau of Mines investigated rapid bubble-pulp separation to improve flotation kinetics. A shallow-depth froth separator was employed to quickly recover the mineral-laden bubbles from a mixture of ore, water, and air bubbles. The shallow depth minimized the rising distance required to recover even the smallest size bubbles (100m). Therefore, the slurry remained in the unit only long enough to recover the bubbles before the pulp exited through the conical bottom. Joining this unit with a rapid bubble-particle attachment unit, a rapid flotation system was formed that floated silica from phosphate in one-fifth of the retention time for conventional mechanical cells. The hydrodynamics of the rapid flotation system along with fundamental parameters for scale-up are presented in this paper.
