Abstract (en)

[origin: EP2592177A1] Provided is a precious metal recovery device for recovering precious metals from waste fluids containing precious metals using an electrolytic method that can allow uniform precious metals to be deposited stably by suppressing the defect of the short circuit because of the variability in the amount of deposition or deposited particles caused by current abnormality or because of abnormal deposition of precious metals caused by current concentration, and its recovery method. In a precious metal recovery device including a cylindrical expander cathode disposed along an inner circumference of a metallic container that constitutes an electrolytic bath, and a cylindrical expander anode disposed along an outer circumference of the pipe-shaped anode, an upper section of the expander cathode is connected and secured to an upper shoulder section of the metallic container in an inverted L-shape in cross section, a lower section of the expander cathode is connected and secured to a bottom section of the metallic container, and both ends of the expander anode are connected and secured to the pipe-shaped anode in a U-shape in cross section.
