Arsenopyrite (FeAsS) is a mineral present in most of the world's mineral deposits, polluting both the environment and base metal concentrates. In this research work, the characterization of FeAsS depression during collectorless flotation, in the presence of mixtures of Al2(SO4)3 and Na2SiO3, in a slightly acidic environment was studied. The results indicate that the arsenopyrite used consists of a single mineralogical phase. The use of mixtures of 0.1, 0.2 and 0.4 g/ton of each reagent, depresses by 28% w/w the presence of this phase in the concentrate. Meanwhile, the % of cumulative collectorless flotation, and without depressant reagents was 77.5%, while in the presence of depressants (Al2(SO4)3/Na2SiO3) it was 49.5%. The pulp potential Eh (mV) referred to the standard hydrogen electrode to achieve arsenopyrite depression is around + 51 mV.
