Abstract

A system (100) and a method for polishing a metal are provided. The system (100) includes a base assembly (102) and an electrolytic cell assembly (130). The base assembly (102) has a support stand (104) which is mounted on to a connecting element (106). The base assembly (102) further includes a holding cylinder (122) that is provided with a hook (124) or similar kind of means that is adapted to hold an anode fixture (134). The method for polishing a metal using the system (100) includes, providing and preheating a stripping solution which is free of cyanide and is taken in a glass beaker (132) of the electrolytic cell assembly (130). The system (100) and the method are environmental friendly and lead the metal loss to be minimized to a negligible amount.
