N2 - In this work, the study of the collectorless flotation of pyrargyrite is presented to provide information for the selective separation of this mineral. The mineral used consists of a single phase with contents of 59.64% w/w Ag, 22.90% w/w Sb, and 17.46% w/w S. The flotation can be carried out using only 60 mg/L frother agent. The pH plays an important role and higher flotation efficiency is obtained at pH 6 and 10 with 66% w/w and 67% w/w of separation, respectively. Values pH 2, 2.54, and 4.97 depress the flotation of the mineral. The surface depression is attributed to the strong intensity of the absorption bands of the Sb–O bonds, the sulfate ion, and the hydroxyl ion OH− species that give it a hydrophilic character, bonds determined by FTIR.
