Abstract

A process for producing an aluminium-silicon alloy from concentrate containing the corresponding oxides, even if chemically combined with each other and/or with other metal oxides, consisting of reducing said oxides with a carbon-based reducing agent in the presence of a plasma arc burner in a shaft reactor filled with reducing material of suitable size.
