A reduction/collection procedure for the recovery of platinum from aqueous solutions applying metallic iron (in the form of a rotating disk) as reductant and lead or copper ions as reduced platinum collectors was studied. Fundamental kinetic aspects of the process, such as the influence of the pH and of the collector’s concentration on platinum recovery yield, were examined experimentally. The two collectors were compared with respect to the particle size of the precipitant falling from the disk surface. Lead ions seem to give a coarser precipitant compared to copper and increase the pH region at which the reaction takes place. The final product was a mixture of platinum and platinum/lead bimetallic compounds (mainly PbPt).
