Abstract

Method of separating a molten hypoeutectic alloy comprising a base metal A and an alloying element B into two melts, namely a melt comprising solely pure A and a melt comprising a B-enriched alloy with B-contents up to the eutectic composition. The melt is introduced to a bath which is located in an elongate reactor vessel and the temperature of which varies from one end of the vessel, a warmer end at which the temperature is immediately above the melting point of the base metal A, to the other, colder end of said vessel, at which the temperature lies above the liquidus temperature of the desired B-enriched alloy, and in which the temperature of the bath in the intermediate parts of the reactor vessel lies close to the liquidus line in a phase diagram A-B and the composition of said bath varies from substantially pure A at the warmer end of the vessel to a given B-enrichment at the colder end of the vessel. Metal crystals having a lower B-content than the bath are precipitated by internally cooling the bath in intermediate parts of the vessel, and the precipitatedcrystals are caused to move towards the warmer end of the reactor vessel, whereat because the crystals must constantly be in equilibrium with a bath which is progressively poorer in the alloying element B are progressively depleted of the alloying element B, so that a substantially pure base metal A can be taken out at the warmer end of the vessel. A B-enriched melt is simultaneously caused to move towards the colder end of the vessel, whereat A-enriched crystals are constantly formed, so as to enable a melt having the given B-content to be taken out at the colder end of the vessel. The amount of base metal and alloying element removed from the system is replaced by supplying fresh starting material to the reactor vessel at a location where the composition of the bath is the same as that of the starting material, and the temperature of the starting material is regulated to the temperature prevailing at this location.
