According to the invention a process is proposed for purifying low-melting metals from impurities, residing in that a melt of a low-melting metal is treated with an aqueous solution of an inorganic acid or an alkali in the presence of organic compounds with ionogenic groupings. The proposed invention enhances the purity degree of the low-melting metal being purified and at the same time reduces the losses thereof.

Process for purifying low-melting metals from impurities

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.
