REINFORCING ADDITIVE FOR PRODUCTION OF IRON-ORE AGGLOMERATE Russian patent published in 2020 - IPC C22B1/14 C22B7/04

Abstract RU 2735413 C1

FIELD: technological processes.

SUBSTANCE: invention relates to raw material preparation and can be used in production of iron-ore agglomerate. Reinforcing additive for obtaining iron-ore agglomerate is obtained as a result of separation of iron-containing material from converter nickel slag with content of fayalite and magnetite at the following ratio of components, wt%: 2FeO⋅SiO₂ (fayalite) - 40-60; Fe₂O₃ (hematite) - 5-25; FeO⋅Fe₂O₃ (magnetite) - 5-12; Fe (iron metal) - up to 3; SiO₂ - 18-38; CaO - 1.0-10; MgO - 1.0-10; Al₂O₃ - 1.0-4.0; other components - up to 2.

EFFECT: high strength of agglomerate and efficiency of its production.
