ABSTRACT:
Method of taking care of the contents of valuable metals in grindings and other waste products of superalloys. The material is led into a metallic melt, preferably by injecting it by means of a carrier gas. The charge is heated up in the inductive way. The material contains aluminium and/or tantalum, or can these elements be added separately to the charge, thus preventing an oxidation of such valuable metals as vanadium, tantalum and niobium and obtaining a high yield of these elements. After the remelting, aluminium and/or titanium can be selectively oxidized by injecting into the charge oxygen and/or water vapor, a slag having a certain oxygen potential or a metal oxide where the metal has a lower affinity to oxygen as compared with aluminium and/or titanium.
