Abstract

The invention belongs to the technical field of silver electrolytic refining, and discloses a silver electrolytic tank. The silver electrolytic tank comprises a plurality of silver electrolytic tank bodies connected in series, wherein each of anode contact spikes and cathode contact spikes comprises a first bending section, a middle section and a second bending section; the height of the middle sections is equal to the height of conducting bars connection in series among the tanks; a plurality of equidistant clamping groove fixing seats are arranged on each of the front tank edge and the back tank edge; the clamping groove fixing seats on the front tank edge directly face middle points of every two adjacent clamping groove fixing seats on the back tank edge; two clamping sleeves are clamped on each anode contact spike; the positions of the clamping sleeves on each anode contact spike are the same and in one-one correspondence. Thanks to the silver electrolytic tank, a cathode plate and an anode plate can be set to be relatively standard, the scale division of electric current density can be relatively uniform, the use ratio and the production efficiency of the electric current are improved, the operation is simple and feasible, and industrial production is facilitated.

Description

technical field [0001] The invention mainly belongs to the technical field of silver electrolytic refining, and in particular relates to a silver electrolytic cell. Background technique [0002] Silver refining methods mainly include electrolytic refining, wet refining, selective adsorption, etc., among which electrolytic refining is the most commonly used method. The essence of the silver electrolytic refining process is an oxidation-reduction reaction. The coarse silver is used as the anode, the titanium plate or pure silver is used as the cathode, and the silver nitrate is used as the electrolyte. Under the energization of the cathode and anode, the anode coarse silver continuously loses electrons and is oxidized to silver ions , so as to dissolve and immerse in the electrolyte, and at the same time, the silver ions in the solution will continue to move towards the cathode under the action of the electric field, and after reaching the cathode, they will obtain electrons a...
