Abstract

The invention relates to a process for separating the constituents of an alloy, especially an alloy comprising a refractory base metal and at least one nonrefractory additive metal, which consists in: PA1 heating said alloy by means for preferably continuous melting and casting of metals, while avoiding any chemical action on said alloy, and to at least one temperature and under controlled atmosphere permitting the boiling of at least one additive metal, PA1 collecting the distillation vapors of at least one additive metal, and PA1 collecting, at the exit of said means for preferably continuous melting and casting, the substance resulting from the removal of at least one additive metal from the alloy. It also relates to a device for separating the constituents of an alloy comprising a refractory base metal and at least one nonrefractory additive metal.
