A continuous melting process wherein aluminum can scrap or other charge is introduced into a moving stream of superheated molten aluminum and thereby rapidly melted, the stream then being subjected to the fluxing action of a gaseous flux substantially immediately upon the melting of the charge. The gaseous flux comprises a non-reactive gas such as argon preferably along with a reactive chlorinaceous gas such as chlorine or another suitable halogen.
