| Abstract | Pequi (Caryocar brasiliense) is a Brazilian oleaginous fruit, rich in fatty acids, with a predominance of oleic and palmitic acids. The fruit is composed of three major parts: the outer mesocarp (or white pulp), the inner mesocarp (or yellow pulp), which is very appreciated in the local cuisine, and the nut. The oil extracted from the nut (43.59 oleic and 43.76% palmitic acid) or from the yellow pulp (55.87 oleic and 35.17% palmitic acid) are used not only for nourishment, but also as a medicinal product and in cosmetic formulations. The white pulp does not have any commercial application being a residue. This paper proposes to use the oil from pequi’s yellow pulp as a collector in apatite microflotation, due to its rich fatty acid composition. The oil was saponified with NaOH and then applied in microflotation tests using a modified Hallimond tube and pure samples of apatite. The results indicate that pequi’s yellow pulp oil can be used as a collector in the froth flotation of this mineral (recovery greater than 95% for concentrations between 5 and 15 mg/L). |
