PLANT FOR SILVER EXTRACTION FROM SILVER-BEARING ALLOY Russian patent published in 2016 - IPC C25C1/20 C25C7/00 

FIELD: metallurgy.

SUBSTANCE: claimed plant comprises the electrolytic cell, anode and cathode current lead, anode cell to load the silver-bearing alloy, vibrator and electrolyte vessel fitted in the thermostat and provided with peristaltic pump for electrolyte circulation. Said vibrator consists of ultrasound source composed by the rod-type magnetostrictor and ultrasound emitting waveguide system secured vertically at the electrolytic system bottom. Said system is shaped to cone with upper hemispherical part with ultrasound emitting flat surface and inner channels. Aforesaid anode cell is spaced from said ultrasound-emitting flat surface by the distance multiple of half the wavelength. Note here that the distance from the ultrasound-emitting flat surface to stiff joint of ultrasound emitting waveguide system at the electrolytic chamber bottom.

EFFECT: higher efficiency of silver extraction, reduced amount of foreign impurities.
