Definitions
- an object of the present invention is to provide a precious metal recovery device and a precious metal recovery method capable of allowing uniform precious metals to be deposited stably so as to be convenient for dissolution during the refining of recovered substances by suppressing the defect of the short circuit because of the variability in the amount of deposition or deposited particles caused by current abnormality described above or because of abnormal deposition of precious metals caused by current concentration described above. Furthermore, another object of the present invention is to provide a precious metal recovery device and a precious metal recovery method capable of allowing precious metals to be deposited uniformly and stably, thereby recovering the precious metals efficiently.
- each of the metallic container and the expander cathode is made of one, two or more kinds of metals selected from a group consisting of titanium, tantalum, niobium, zirconium and hafnium or alloys thereof.
- FIG. 1 An embodiment according to the present invention will be described below referring to a sectional diagram ( FIG. 1 ) showing a precious metal recovery device for recovering precious metals from a waste fluid containing precious metals by electrolysis.
- a precious metal recovery device 1 since the upper section of an expander cathode 12 is connected and secured to the upper shoulder section of a metallic container 10 in an inverted L-shape in cross section and the lower section thereof is connected and secured to the bottom section of the metallic container 10, it is possible to suppress the short circuit to the anode due to the wobbling of the cathode or to suppress the short circuit due to abnormal deposition caused by current abnormality or drop of deposited substances.
- the metallic container 10 and the expander cathode 12 should be made of one, two or more kinds of metals selected from the group consisting of titanium, tantalum, niobium, zirconium and hafnium or alloys thereof.
- metals or alloys other than those described above are used, if aqua regia that is frequently used when precious metals (gold, platinum, etc.) electrolyzed and deposited on the metallic container 10 and the expander cathode 12 are dissolved and recovered from the electrode for the purpose of refining after the recovery, the metallic container 10 and the expander cathode 12 may be dissolved in some cases.
- the length of the expander anode 13 according to the embodiment should be a length obtained by multiplying 0.5 to 0.95 to the length of the expander cathode 12.
- the length of the expander anode 13 is more than the length obtained by multiplying 0.95 to the length of the expander cathode 12
- deposited powdery precious metals accumulate at the bottom section of the metallic container 10; as a result, not only a short circuit is apt to occur, but also abnormal deposition occurs at the bottom section of the expander cathode 12.
- the length of the expander anode 13 is less than the length obtained by multiplying 0.5 to the length of the expander cathode 12
- a large imbalance occurs in the current distribution on the cathode, the deposition amounts and the shapes of deposited metals become non-uniform, and dissolution time for refining becomes long, for example, thereby causing a decrease in recovery efficiency.
- the length of the expander anode 13 should be a length obtained by multiplying 0.7 to 0.95 to the length of the expander cathode 12.
- the metallic container 10, the expander cathode 12 and the continuous metal plates of the cathode are made of titanium, and the pipe-shaped anode 11, the expander anode 13 and the continuous metal plates of the anode are made of titanium as a base material and plated with iridium.
