FIELD: ferrous metallurgy, in particular, utilization of metallurgical wastes which may be used as additional raw material in blast furnace and steel melting production.
SUBSTANCE: method involves mixing scale-and-oil containing muds of secondary sumps of rolling shops with detergent solution; washing resultant mixture; separating washed scale from liquid component of mixture-suspension; dehydrating washed scale until residual water content in scale reaches 10-14%; pressing mixture of semi-dried scale and binding additives and simultaneously acting upon it by vibrating motions provided in two mutually perpendicular planes; separating suspension into components; cleaning surface oil-containing layer from inclusions and feeding into oil receptacles; returning oil-free suspension component for mixing with basic mud.
EFFECT: increased efficiency in extracting of iron-containing material and producing of briquettes and mineral oil from scale-containing muds of secondary sumps of rolling shops.
