Abstract
Den foreliggende oppfinnelse vedrører en elektrolytisk fremgangsmåte for raffinering av metaller med et smeltepunkt over ca. 1000?C, særlig silisium, hvor det fremskaffes et øvre smeltet sjikt av det samme metallet som metallet som skal raffineres, hvilket sjikt utgjør en katode, et nedre smeltet sjikt av metallet som skal raffineres og minst ett metall mer edelt enn metallet som skal raffineres, hvilket nedre sjikt utgjør en anode, hvilken legering har en høyere tetthet enn metallet som skal raffineres, og en smeltet oksidbasert elektrolytt inneholdende SiO2, hvilken elektrolytt er i smeltet tilstand og har et smeltepunkt under driftstemperaturen for prosessen, hvilken elektrolytt har en tetthet mellom tettheten for det øvre og det nedre smeltede sjikt, føre en likestrøm fra anoden gjennom elektrolytten til katoden hvorved metallet som skal raffineres beveges fra anoden og avsettes i smeltet tilstand ved katoden.The present invention relates to an electrolytic process for refining metals having a melting point above ca. 1000 ° C, especially silicon, where an upper molten layer of the same metal as the metal to be refined is provided, which layer is a cathode, a lower molten layer of the metal to be refined and at least one metal more noble than the metal to be refined. , which lower layer constitutes an anode, which alloy has a higher density than the metal to be refined, and a molten oxide-based electrolyte containing SiO2, which electrolyte is in the molten state and has a melting point below the operating temperature of the process, which electrolyte has a density between the densities for the upper and lower molten layers, direct a direct current from the anode through the electrolyte to the cathode whereby the metal to be refined is moved from the anode and deposited in the molten state at the cathode.
