Description

technical field [0001] The invention relates to an electrolytic silver powder preparation device, in particular to an electrolytic silver powder preparation system. Background technique [0002] Electrolytic silver is a common method for preparing high-purity silver from crude silver containing impurities by electrolysis. Electrolysis is a process in which the electrolytic solution or molten electrolyte undergoes oxidation-reduction reactions on the cathode and anode under the action of direct current. During this process, electrical energy is continuously converted into chemical energy, because different metals have different theoretical electrode potentials. Generally speaking, the higher the theoretical potential of metal ion precipitation, the easier it is to precipitate on the electrode, and the lower the theoretical potential of metal ion precipitation, the less likely it is to precipitate on the electrode. Therefore, as long as certain electrolysis conditions are con...
