The pH, is a critical variable and influences the surface state of the floated ore particles and the flotation efficiency, jamesonite is a lead sulphosalt, antimony with iron contents Pb4FeSb6S14. In this investigation, the study of the surface state of jamesonite was carried out, using infrared spectroscopy of particles obtained in the collectorless flotation in acid, neutral and alkaline medium. In the alkaline medium, the mineral flotation decreases or is depressed, mainly due to the oxidation of the superficial iron, forming oxy hydroxide iron, goethite α-FeOOH, considered as a hydrophilic specie, as well as the division of the main sulphate band indicating metal sulphate formation. Meanwhile, when the collectorless flotation is at pH 6 and 7.8, a recovery of 70% w/w is reached, and the absorption bands of the species with covalent bond, are significantly attenuated.
