摘要 |
Process for producing a refined metal or metalloid, comprising: an electrolysis step of, in an electrolytic bath set in a container for an electrolysis in which a material comprising a metal element or metalloid element and impurities acts as an anode, and an alloy comprising the same metal element or metalloid element as the metal element or metalloid element and a medium metal that does not substantially form a solid solution with the metal element or metalloid element and having a complete solidification temperature lower than the melting point of the metal element or metalloid element acts as a cathode, performing electrolysis at a temperature at which the alloy can be a liquid phase; withdrawing a part or the whole of the alloy of the cathode to an outside of the container; cooling the withdrawn alloy at a temperature higher than the complete solidification temperature and lower than the electrolysis temperature; and a recovery step. |
