Hydrophile-Lipophile Balance). Frothers located on the left
side of this diagram are known to be selective in flotation,
while those situated further to the right exhibit properties
characteristic of strong flotation frothers. The former froth-
ers are effective for the flotation of very fine particles, while
the latter can achieve higher recoveries and better overall
performance (Laskowski, 2003).
Figure 7(b) illustrates the eight products developed by
Locus Mining, plotted with their Hydrophilic-Lipophilic
Balance (HLB) against molecular weight, similar to the
research conducted by Laskoski. As shown, the products
cover a broad range of characteristics, with two products—
FrothBoost I-h and FrothBoost A—even extending beyond
the limits initially established by Laskoski. It is important
to note that some of these products also exhibit significant
collecting power, presenting dual characteristics for these
biosurfactants as both frothers and collectors.
Denver Cell Laboratory Tests Results
Results from the Denver cell were conducted in duplicate:
one set of tests was performed using regular flotation meth-
ods, while the other set utilized kinetic testing. Below is a
grade-recovery curve that shows the average of both final
results. Additionally, the average for the usual process plant,
along with the standard deviation, a 95% confidence inter-
val, and references for maximum and minimum produc-
tion levels, are plotted on the same graph.
