Abstract: Macaúba (Acrocomia Aculeata) is a palm tree typical of the Brazilian savanna with great socioeconomic interest due to its high capacity of vegetable oil production with high levels of fatty acids. This paper evaluated the technical viability of saponified macaúba’s nut oil (SMNO) as a collector in apatite’s micro flotation in Hallimond tube, being the oil chemically characterized and saponified before its utilization. 

Tests were performed varying the solution pH (8, 9 and 10) and collector concentration (2.5, 5.0, 7.5 e 10 mg/L). To compare the obtained results with SMNO the industrial collector Clariant’s Flotigan 5806 was used in the same tests conditions. 

Results shows that SMNO reached the highest recoveries rates of apatite in pH 8 and 9, particularly at the concentrations 7.5 and 10 mg/L. When compared to Flotigam 5806, the MNO showed lower recoveries at all pHs and concentrations tested.
