METAL RECOVERY REACTOR AND METAL RECOVERY SYSTEM

摘要

The present invention relates to a metal recovery reactor and a metal recovery system. The metal recovery device according to the present invention comprises an electrolytic cell which receives a solution containing metal ions from the outside, and which reduces and precipitates the metal ions of the solution on the surface of a cathode when the solution is supplied to a reaction space formed between an anode and the cathode surrounding the anode. The cathode comprises a main cathode and an auxiliary cathode positioned inside the main cathode and capable of being detached and attached from the main cathode.
