PROBLEM TO BE SOLVED: To provide a wet electrolytic collection method and facility for gold and silver which can improve the recovery efficiency of gold and silver even if impurities are contained in ore.SOLUTION: A facility for collecting gold and silver from ore by wet electrolysis using a solution S comprises a storage tank 2 which stores the solution S, an ore holding part 2g which is installed in the storage tank 2 and on which the ore is put, and a pair of electrodes 11, 12 which are disposed in the storage tank 2. An anode electrode 11 in the pair of electrodes 11, 12 is installed on a surface of the ore holding part 2g on which the ore is put. Since gold and/or silver can be brought into contact with the anode electrode 11 when the ore is put on the ore holding part 2g, the gold and/or silver can be dissolved in the solution S in a short time by applying a voltage between the pair of electrodes 11, 12 even if the gold and/or silver are/is large in grain size.SELECTED DRAWING: Figure 1 |
