FIELD: public utilities; construction industry; metallurgy. SUBSTANCE: slag processing method includes loading of slags into electric-arc furnace at temperature of 600-900 C and its melting with feed of reducing agent the quantity of which is 100-125 per cent of amount required stoichiometrically. Melting results in obtaining the slag with chemical composition of 
by mass. EFFECT: highly efficient technology, high degree of iron and nonferrous metal extraction, reduced electric power consumption. 2 cl, 1 tbl
