Abstract
The disclosure relates to a method for the beneficiation of an ore in a froth flotation process. The method comprises contacting an ore in a liquid medium to a collector composition comprising a plant-derived liquid decarboxylated rosin acid (DCR) collector. The DCR comprises 40 to 100 wt. % of tricyclic compounds having 18-20 carbon atoms, one or more C═C groups, and m/z (mass/charge) value of 220-280. The DCR has an oxygen content of <5%, a density of 0.9 to 1.0 g/cm3 at 20° C., and an acid value of <50 mg KOH/g.
