The aim of this study was to evaluate the technical feasibility of using macaúba's nut oil as collector in the flotation process of apatite. The macaúba (palm tree typical of the Cerrado which can be found in the extensive area of the Brazilian territory) offers broad utility in several areas (medicine, food, cosmetics, etc.) and has attracted great interest for their high socioeconomic capacity for the production of vegetable oil and with high levels of fatty acids. To that end, the macaúba's nut oil was subjected to the process characterization and saponification, and was applied in trials microflotation of apatite mineral. Finally, the results of the macaúba's saponified nut oil was compared to the collector Flotigam 5806, produced by Clariant, which was also subjected to the same methodological procedures in order to verify its industrial applicability in relation to a collector normally marketed. The results of the apatite recovery for both collectors were tested with analysis of variance (ANOVA), with the purpose to investigate whether the factors pH and concentration of the collector influence on the apatite recovery. The results showed that, compared to Flotigam 5806, macaúba's saponified nut oil was not competitive, and provided lower recoveries of apatite at all pHs and concentrations. For the ANOVA test, it was found that the pH and concentration of the collector factors have greater influence on macaúba's saponified nut oil compared to Flotigam 5806, with respect to the recovery of apatite.
