Abstract
In this work the evaluation of a filter press type Reactor (REOV-01) with Ti electrode was realized, applied in the silver recovery from industrial wastes. Macroelectrólisis studies were performed at different flow velocities with empirical and dimensionless correlations and parameters. The results of the variation of the concentration of Ag at different flow linear velocities allowed the determination of the mass transfer coefficients of silver (order of 10exp-5) for Ti electrode, which are consistent with the literature. Chronopotentiometric studies showed that the Ti electrode performed better for the recovery of silver because to a current of -150 mA during 210 minutes was achieved 99.8% of silver recovery. The current efficiency values above 100% indicated that the electrochemical process is coupled to an electroless process. The results showed low energy consumption and high space-time yield values indicating that the REOV-01 presents an excellent performance in the recovery of silver.
