    The majority of Brazilian phosphate rock reserves are concentrated in the states of Minas Gerais and Goias, which also hold much of the country’s Jatropha cultivation (Jatropha Curcas), a plant rich in fatty acids, predominately linoleic acid, followed by acid oleic and palmitic acid. Jatropha Curcas is a fruit that contains three chestnuts which have oil content ranging from 22-48%. Due to its toxicity it is not edible, which makes it economically viable. Besides the new exploration of oil for mining purposes, material resulting from the pressing is being explored in the fields of biofuel, ink and varnish scanning. This article introduces the application of Jatropha Curca oil (JCO) extracted by pressing as collector in microflotation tests, due to the rich composition of fatty acids in nuts. The oil was saponified at high temperature using NaOH, 95% alcohol and then the microflotation tests were made in a Hallimond tube with the use of pure mineral apatite at pH 8, 9 and 10. The results showed better recovery had pH 10 and other recovery points to the two collectors tested showed similar results and over 90% recovery showing that Jatropha Curcas oil can be used as collector in the flotation of this mineral.
