abstract

• The presence of ferric ion in the pulp from the grinding is due to the galvanic reactions that take place between the sulfides and the grinding steel media, decisively influencing the flotation stage. In this research work, the behavior of different iron concentrations in galena collectorless flotation in acid and alkaline medium is studied. The results found indicate the depression of the mineral (27%25 w/w of flotation) in the presence of 25 mg/L of ferric ion at pH 10 and a pulp potential (Eh) of %2b 81 mV, with similar values of Eh and pH, but in the absence of the metal ion, a cumulative flotation of 59%25 w/w is obtained. While at slightly acidic pH 6.0, Eh of %2b 280 mV, and in the presence of 75 mg/L of iron, a cumulative flotation efficiency of 65%25 w/w is obtained. © 2022, The Minerals, Metals %26 Materials Society.
