gold, silver and copper electrochemical recovery and extraction process from aqueous solutions using an electrochemical cell

摘要

"Process for the recovery and electrochemical extraction of gold, silver and copper from aqueous solutions using an electrochemical cell". New process of recovery and electrochemical extraction of gold, silver and copper from aqueous solutions using an electrochemical cell composed of one titanium cathode or composed of a glassy carbon cathode, which is applied directly to solutions with silver and other metal ions. copper, eliminating preconcentration steps that use activated carbon, and without the use of any chemical reagent added to the process, where the recovery of metallic materials is effected through the oxy-reduction reactions that occur on the electrode surfaces of an electrochemical cell. powered by an external source of electric current / potential due to the imposition of the potential difference and / or an electric current applies to the electrolytic cell.
