FIELD: metallurgy.
SUBSTANCE: iron ore pellets for metallurgical production contain ferriferous material and binder, and also undersized coke. The binder in pellets is slack lime, and the ferriferous material is slime and/or dust of gas purifications of domain, martin, converter or electric steelmaking productions or their mix. The amount of undersized coke 1.2-1.4 times exceeds total amount of iron and zinc in ferriferous material, and the amount of slack lime is 0.14-0.20 from total of undersized coke and ferriferous material.
EFFECT: improvement of efficiency of recycling of metallurgical production.
