    Author : Anna Semykina; Seshadri Seetharaman; Gabriella Tranell; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oxidation; metallurgical slag; recycling; FeO; iron recovery; manganese recovery; manganese ferrite; nano-ferrites; oxidation process; TTT; crystallization; kinetics studies; thermodynamic studies; modelling; cold-model studies; electromagnetic buoyancy force; Metallurgical process engineering; Metallurgisk processteknik; Metallurgical process and manufacturing engineering; Metallurgisk process- och produktionsteknik; Materials science; Teknisk materialvetenskap;

    Abstract : In the modern practice, a sustainable development strategy in a domain of wasteutilization is shifting its focus from a general completeness of recycling to a morespecific attention to efficiently utilize elements in the wastes. This is well-illustrated bythe steelmaking slag industries. READ MORE
