The pressure oxidation process (POX) is frequently employed as a pre-oxidation step for refractory gold ores. This stage is responsible for the generation of a large volume of liquid effluents. Those are characterized by its high acidity and substantial metal content. Thus, in this study a cationic resin was employed, in different concentrations, to recover metals from a synthetic effluent. High correlation coefficients were found for the relationship between resin concentration and metal removal efficiency (R2 > 89). Higher removal efficiency was observed for aluminum (97%), followed by manganese (91.7%), calcium (85.7%), nickel (83.8%), iron (83.7%), copper (82.7%) and manganese (82.6%). Showing that the cation exchange resin was able to recover high concentrations of metals in a complex medium.
