Flotation kinetics explores how mineral recovery rates
in froth change over time. First-order kinetics indicates that
flotation rate is proportional to the concentration of non-
floated minerals, resulting in an exponential decrease in
flotation rate over time. (Napier-Munn and Wills, 2005).
Figure 3 shows how noteworthy that the flotation speed
remains unaffected, given the close proximity of the curves.
However, when ultrasound is employed, the rate of quartz
removal increases significantly compared to its absence,
revealing a larger exposed surface area of this mineral
CONCLUSIONS
Employing innovative tools is essential to optimize metal-
lurgical recovery, and in this regard, ultrasound proves to
be a potent solution by ensuring the proper dispersion of
particles, thereby enhancing the selective action of the new
collector reagent. To enhance the efficiency of the recovery
process, it is recommended to use more diluted pulps.
