Abstract
Den foreliggende oppfinnelse vedrører en elektrolytisk fremgangsmåte for fremstilling og raffinering av metaller med et smeltepunkt over ca. 1000ºC, særlig silisium, hvor det fremskaffes til en første elektrolysecelle, et øvre elektrolyttsjikt omfattende en første elektrolytt, et nedre sjikt av en smeltet legering omfattende en legering av det metall som skal raffineres og minst et metall mer edelt enn metallet som skal raffineres. Det nedre legeringssjikt utgjør en katode i den første elektrolysecellen, og en anode er anordnet i det øvre smeltede elektrolyttsjiktet. En andre elektrolysecelle er fremskaffet med et øvre smeltet metallsjikt av det samme metallet som metallet som skal raffineres, hvilket sjikt utgjør en katode, et nedre smeltet legeringssjikt som utgjør en anode hvilken legering har en høyere tetthet enn metallet som skal raffineres og et mellomsjikt av en smeltet elektrolytt med en tetthet mellom tettheten for det øvre og nedre smeltede sjikt. Begge elektrolyttene er oksidbaserte elektrolytter inneholdende oksid av det metallet som skal raffineres og elektrolyttene er i smeltet tilstand og har et smeltepunkt under driftstemperaturen for prosessen. Råmateriale omfattende et oksid av metallet som skal raffineres tilsettes til den første cellen, og likestrøm tilføres gjennom anoden til katoden slik at metallet som skal raffineres beveges fra anoden og avsettes i smeltet tilstand ved katoden. De to cellene kan drives i to separate trinn. Et trinn kan fremstille legering og det andre trinn kan raffinere metallet fra legeringen.The present invention relates to an electrolytic process for the production and refining of metals having a melting point above ca. 1000ºC, especially silicon, where it is provided to a first electrolytic cell, an upper electrolyte layer comprising a first electrolyte, a lower layer of a molten alloy comprising an alloy of the metal to be refined and at least one metal more noble than the metal to be refined. The lower alloy layer constitutes a cathode in the first electrolytic cell and an anode is provided in the upper molten electrolyte layer. A second electrolytic cell is provided with an upper molten metal layer of the same metal as the metal to be refined, which layer constitutes a cathode, a lower molten alloy layer constituting an anode which has a higher density than the metal to be refined, and an intermediate layer of a molten electrolyte with a density between the density of the upper and lower molten layers. Both electrolytes are oxide-based electrolytes containing oxide of the metal to be refined and the electrolytes are in the molten state and have a melting point below the operating temperature of the process. Raw material comprising an oxide of the metal to be refined is added to the first cell, and direct current is supplied through the anode to the cathode such that the metal to be refined is moved from the anode and deposited in the molten state at the cathode. The two cells can be operated in two separate steps. One step can produce alloy and the other step can refine the metal from the alloy.
