Jan 12, 2018 Flotation is considered to be a physico-chemical process. Equipment in the form of mechanically or pneumatically agitated tanks or cells generate air bubbles, which provides the physical aspect. The chemical aspect is provided by reagents, which vary the surface properties of minerals and of the slurry medium for separation of valuable minerals ...
From mass balancing, 55.4 wt. of the ground tailings material was 75 m, and this fraction was analyzed using laser diffraction. Based on the three solute samples analyzed, it was observed that the average particle diameter at 80 was 5.85 m Figure 8 , meaning a substantial reduction in particle size had resulted from the grinding.
