Electrochemical behavior of galena in the presence of ...
Abstract A study of the electrochemical behavior of galena and the effect of the Ca2+ and SO42− species on the mineral behavior at different pH, was carried out using carbon paste electrodes. The Ca2+ and SO42− ions were used to simulate the species that are most concentrated in the recycled water of sulfide mineral flotation processes. By means of electrochemical and SEM analysis, it was ...
