Abstract

The present invention relates to an electrolyser for electrowinning of non-ferrous metals comprising a plurality of intercalated elementary cells, wherein each elementary cell is equipped with a device suitable for the detection of anomalies in the distribution of electric current to the respective anode.

Description

technical field [0001] The present invention relates to an electrolysis device comprising a plurality of basic units suitable for metal electrowinning, in particular for the electrolytic production of copper and other non-ferrous metals starting from an ionic solution, and to an electrolysis device equipped with such an electrolysis device equipment. Background technique [0002] Electrochemical equipment for non-ferrous metal deposition, such as equipment for electrowinning and refining of metals, is also referred to as electrowinning equipment and electrowinning equipment, respectively, and such equipment typically uses one comprising a plurality of base units or multiple electrolysis units, wherein each basic unit contains an anode and a cathode. [0003] In electrolysis plants intended for use in the apparatus described above, anodes and cathodes are generally arranged in an electrolytic cell in alternating positions and parallel to each other. Each electrode is mechan...
