Abstract Scope Wastewater from nickel lateritic process still has values metals that could be recover. Using ion exchange method to separate selective metals, the main problem is the iron precipitation, whereupon reduce the resin efficient. The goal of this research was to make iron soluble by reducing Fe+3 to Fe+2. Reducing agents sodium dithionite and sodium metabisulfite were used and the potential was verified using as a reference the iron’s Pourbaix diagram. The pH was ranging between 0,5 to 2, the reducing agent’s concentration was ranging between 0,5 to 2M, the reaction time was ranging between 30 to 420min and the temperature was ranging between 25 to 60⁰C. The results show the ideal point of reduction Fe+3 to increase the resin efficiency. Thereby, the batch process of ion exchange using these parameters was studied and temperature influence were also studied, which presented higher efficiency than before.
