1. Introduction. With the continuously high demand for energy and metals around the world, high-grade ore deposits are sharply depleted (Peng and Bhambhani, 2021).This forces the industry to transition into the processing of complex and lower grade ores (Mudd, 2010).As ore grades decline, more challenges arise in mineral processing …

It is possible to increase the rise rate of the formed flotation aggregates, and thereby enhance the efficiency of flotation treatment via secondary saturation of the flotation cell with d b = 0.1-0.3 mm air bubbles. The air bubbles of 0.02-0.07 mm diameter float up in laminar flow regime but create light turbulence in the flotation cell.
