Background
In the electrical appliances, most of the electrical appliances adopt a circuit board as a control unit, the circuit board contains a large amount of copper and tin, and the copper-rich copper plate prepared after disassembly has copper content of about 90% and tin content of about 10%. Since tin is recovered at a higher price than copper, if the tin-rich copper plate is recovered as copper plate, a defect is caused, and thus it is necessary to recover tin and copper separately from the tin-rich copper plate.

Unlike the cast anode, in the case of the frame anode electrolysis, new scrap copper particles can be added to the frame as the scrap copper particles dissolve in the frame, so that the electrolysis operation does not need to be interrupted, and the electrolysis production can be continuously performed. Meanwhile, the frame type anode electrolysis does not have anode residue. Not only eliminates the refining process, but also improves the electrolytic operation of the cast anode.
Copper ions are generated by electrolyzing copper at an anode through the difference of the potential of copper and other metals, and copper is generated by obtaining electrons from the copper ions at a cathode and is enriched on a cathode plate, so that the copper is electrolytically refined. When the production process is used for separating tin and copper, the tin can form anode slime to be deposited at the bottom of the electrolytic tank, the anode slime can be gradually increased in the electrolytic process, the flow of electrolyte is easily affected when the anode slime is excessive, and then the process of transferring copper ions from an anode to a cathode is affected, so that the electrolytic efficiency is reduced. Meanwhile, because the tin is precipitated at the bottom of the electrolytic tank and mixed with the electrolyte, the tin is not easy to recover. It is therefore necessary to redesign an electrolytic recovery device to solve the above-described problems.
