  2. 21. Influences of alumina on fayalite-type slags properties : an experimental study on leaching and melting behaviours

    Author : Sina Mostaghel; Dan Berg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Abstract : Recycling of secondary raw materials by non-ferrous metal producers is steadily increasing. These materials inevitably introduce various impurities to the production furnaces, which can change the chemical composition, and thereafter, the physical and chemical properties of the products and by-products.

  4. 22. Steelmaking slags as raw material for sulphoaluminate belite cement

    Author : Daniel Adolfsson; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Abstract : The present work was undertaken as part of the research in the Minerals and Metals Recycling research centre, MiMeR. The course of the thesis is attributed to metallurgical slags from the steelmaking industry and the possible use of such by-products as raw material for sulphoaluminate belite cement (SAB).

  5. 23. Degradation of mullite based materials by alkali containing slags

    Author : Jesper Stjernberg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materialteknik; Engineering Materials;

    Abstract : Iron is one of the most important resources that can be found in the lithosphere; 90 % of all metal ores extracted are iron ore. Many steps are included in the extraction from iron ore to metallic iron, where the processes vary between different producers. Iron ore pellets, are a prepared burden material for ironmaking in the blast furnace. READ MORE

  6. 24. Enhanced phosphorus removal from wastewater using virgin and modified slags : performance, speciation and mechanisms

    Author : Minyu Zuo; Gunno Renman; Jon Petter Gustafsson; Lars Lövgren; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AOD; EAF; BFS; Calcium phosphate; XANES; slag mineralogy; Mark- och vattenteknik; Land and Water Resources Engineering;

    Abstract : Argon oxygen decarburization slag (AOD) was tested in batch and column experiments to investigate its phosphorus (P) removal performance. The effects of factors such as AOD dose, initial P concentration of the feeding solution, and aging on the P removal ability of the slags were analyzed. READ MORE

  7. 25. Leaching of water-granulated iron silicate slags and their compounds : A study of synthetic and industrial slag systems

    Author : Jakob Kero Andertun; Fredrik Engström; Caisa Samuelsson; Pasi Peltola; Bart Blanpain; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Abstract : Copper smelter slag is a residue product of the pyrometallurgical extraction of copper. Due to its physical properties, the iron silicate type of copper smelter slag has many possible application areas, e.g., different aggregates and abrasives. READ MORE
