Abstract
A system for recovering silver as a free metal from silver-bearing liquid. The silver recovery system includes a holding tank for receiving silver bearing liquid having an opening in its top and a removable cover for closing the opening. A pair of silver recovery cartridges are carried by the cover and are connected together for serial flow. Each silver recovery cartridge contains a source of ions above silver in electromotive force series for reacting with silver-bearing liquid so that silver is recovered therein. A pump is secured to the cover for delivering silver-bearing liquid from the holding tank to the silver recovery cartridges.
Claims17
A system for recovering silver from a silver-bearing liquid, comprising:
- a holding tank for receiving silver-bearing liquid, said holding tank having an opening in its top;
- a removable cover for closing said opening;
- a first cartridge carried by said cover, said first cartridge adapted to contain a source of ions above silver in electromotive force series for reacting with silver-bearing liquid so that silver is recovered within said first cartridge;
- a second cartridge carried by said cover and serially connected with said first cartridge, said second cartridge adapted to contain a source of ions above silver in electromotive force series for reacting with silver-bearing liquid so that silver is recovered within said second cartridge;
- and,
- a pump, having an inlet in fluid communication with said holding tank and an outlet in fluid communication with said first cartridge, secured to said cover for delivering silver-bearing liquid from said holding tank to said first and second cartridges.
