Abstract
Se propone una nueva forma de operar la reducción de metales disueltos, particularmente Cu+2 a Cu°, en que se regula el efecto de la capa límite de difusión optimizando las variables que determinan la movilización del Cu+2 hacia el cátodo y la condición de estabilidad termodinámica de la reacción de reducción de Cu+2 a Cu° (o del metal de interés) en la superficie catódica. Se realiza mediante el control de la concentración de Cu+2 alimentada a la celda, el flujo de electrolito que circula en el espacio ánodos/cátodos y de la corriente alimentada por el rectificador. El uso de rangos operacionales de potencial catódico y/o la mantención de un cociente adimensional (denominado ‡) dentro de ciertos márgenes, prefijados de acuerdo al producto que se desee del proceso.
