Abstract

Procedimiento y equipo para la electrodeposición de oro o aleaciones de oro La reposición de oro se lleva a cabo haciendo recircular continuamente el electrolito alcalinocianurado entre la celda electrolítica de electrodeposición (1) y una celda electrolítica auxiliar (2) en cuyo ánodo (21) se colocan láminas de oro (22), de manera que el cianuro potásico libre que se forma en el electrolito como consecuencia del proceso de electrodeposición se combina con oro en dicha celda electrolítica auxiliar (2) para formar el cianocomplejo K(Au(CN){sub,2}). El equipo comprende una celda electrolítica de electrodeposición (1) y una celda electrolítica auxiliar (2) que permite reponer el oro de forma continua. Las características de la invención permiten efectuar un recubrimiento de espesor y composición uniforme, manteniendo los costes, y en particular los costes de reposición de oro, en niveles reducidos.
