The investigation results suggest that flotation is generally affected by the concentration of bacterial biomass used in the micro-flotation cell. Apatite recorded a high flotation efficiency of around 90%, while quartz achieved 14% flotation at pH 5 and a high concentration of bacterial biomass under identical experimental conditions.
