  • Electrolyzer for producing and refining metals
    Patent number: 4002550
    Abstract: An electrolyzer has an electrolyte tank wherein are accommodated a cathode of the refined metal and an anode of the metal being refined located equidistant from the cathode over shelves of a box-type cross-section arranged in stepped relationship, the shelves being mounted with a clearance relative to the tank inner surface. To circulate the metal there is a pump feeding the metal being refined, from a metal collector situated in the tank bottom, to the top shelf wherefrom the metal flows by gravity over the shelves located therebeneath back into the metal collector. During the circulation of the metal being refined in the electrolyte it dissolves electrochemically and a refined metal deposit is formed on the cathode.
