Mill scale can be considered a cheap material for the removal of toxic metals due to its high content in iron oxides and metallic iron. A study of the removal of Cd<sub>+2</sub>, Zn<sub>+2</sub>, Pb<sub>+2</sub> y Cu<sub>+2</sub> ions from aqueous solutions was made, studying several variables that affect the process. The removal of cadmium, zinc and lead corresponding to a superficial adsorption process, was evaluated using the theories of Langmuir and Freundlich. The removal of copper occurs through a process of oxidation-reduction or cementation (Cu<sub>+2</sub>/Fe<sub>0</sub>). The possibilities of desorption were studied too.}, number={5}, journal={Revista de Metalurgia}, author={Martín, M. I. and López, F. A. and López-Delgado, A. and Pérez, C. and Alguacil, F.
