FIELD: manufacture of metal containing alloying additive.
SUBSTANCE: method for producing metal containing additive comprises steps of mixing copper melting slag with ammonium bifluoride in quantity consisting of 100 -120% of stoichiometric quantity and necessary for interaction with silicon oxide and metal sulfides present in said slag; heating charge till temperature 400-500°C and soaking it at such temperature until complete separation of silicon and sulfur in the form of volatile ammonium hexafluorosilicate and hydrogen sulfide.
EFFECT: possibility for using slag of copper melting production as metal-containing additive.
