Abstract Scope |
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 60.22 % w/w Ag, 19.08 % w/w Sb, 16.86 % w/w S and 3.84% w/w% Cu. 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. The acid values 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. |
