FIELD: slag refining. SUBSTANCE: ferrovanadium slaking slag is mixed together with iron blast-furnace slag in weight mixing ratio of 1: (1-3), respectively, with silica-containing additive added to ferrovanadium slaking slag in the amount of 0.05-0.15 % by weight based on the total ferrovanadium slag before mixing such two molten slags. EFFECT: increased efficiency. 1 cl, 2 tbl
