Abstract

Den foreliggende oppfinnelse tilveiebringer en metode ved hjelp av hvilken et metalltåkedannende metall oppløst i en del av "en smeltet saltblanding bestående av et eller flere metalltåkedannende metallholdige smeltede salter" (generelt et smeltet salt) kan fjernes og overføres til en ytterligere del av det smeltede salt for å øke konsentrasjonen derav. Metoden kan følgelig anvendes som et middel for å behandle smeltede salter innenfor forskjellige industrielle områder hvori metalltåkedannende metallholdige smeltede salter som f.eks. Ca eller Na håndteres. Spesielt, når metoden anvendes i fremstilling av Ti ved hjelp av reduksjon med Ca, kan det Ca som er oppløst i det smeltede salt som skal mates til en elektrolysecelle hurtig fjernes (gjenvinnes) og Ca dannelseseffektiviteten under elektrolysen av det smeltede salt kan forbedres. Følgelig kan Ca dannelse og TiCl4 reduksjon i elektrolysen av det smeltede salt effektivt gjennomføres og en stabil operasjon i en kommersiell skala er mulig. Metoden kan således effektivt anvendes i produksjon av Ti eller en Ti legering ved hjelp av reduksjon med Ca.The present invention provides a method by which a metal mist-forming metal dissolved in a portion of "a molten salt mixture consisting of one or more metal mist-forming metal-containing molten salts" (generally a molten salt) can be removed and transferred to a further portion of the molten salt. to increase the concentration thereof. Accordingly, the method can be used as a means of treating molten salts in various industrial fields in which metal-forming metal-containing molten salts such as e.g. Ca or Na is handled. In particular, when the method is used in the preparation of Ti by reduction with Ca, the Ca dissolved in the molten salt to be fed to an electrolysis cell can be rapidly removed (recovered) and the Ca formation efficiency during the electrolysis of the molten salt can be improved. Accordingly, Ca formation and TiCl 4 reduction in the electrolysis of the molten salt can be effectively accomplished and a stable operation on a commercial scale is possible. Thus, the method can be effectively used in the production of Ti or a Ti alloy by reduction with Ca.
