ELECTROLYTIC CELL FOR MANUFACTURING RARE-EARTH METALS Russian patent published in 2017 - IPC C25C7/00 C25C3/34 C22B59/00 

FIELD: chemistry.

SUBSTANCE: electrolytic cell comprises a housing formed with one or more oblique channels in the housing bottom for draining molten rare earth metals. One or more cathodes are suspended in the cell housing in vertical alignment with one or more channels. The respective cathodes of the opposed surfaces are inclined downwardly and outwardly at an angle from the vertical. One or more pairs of anodes suspended in the cell body. Each anode in one or more pairs has a front surface, the deviation from the vertical and spaced apart in parallel alignment with the respective opposite inclined surfaces of one or more cathodes. The electrolytic cell also includes a collection for the reception of molten rare earth metals from the channel. Separation of molten rare earth metals from the cathode (s) and anode (s) prevents contamination of volatile carbon, rising from the anode (s), or the reverse reaction with the exhaust gases.

EFFECT: increased efficiency of energy consumption and the reduction of product contamination.
