  2. 1. 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. 2. 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

  5. 3. A Dissolution Study of Common Ferrous Slag Minerals

    Author : Ida Strandkvist; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Abstract : Slag is a vital part of metal production since it removes impurities from the metal. As slag is continuously produced, the options are either to dispose slag in landfill or acknowledge slag as a product. READ MORE

  6. 4. Alloy element redistribution during sintering of powder metallurgy steels

    Author : Abdul Malik Tahir; Gustav Amberg; Jose Manuel Torralba; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cu redistribution kinetics; diffusion; phase field modeling; powder metallurgy; swelling; liquid phase sintering; Teknisk materialvetenskap; Materials Science and Engineering; Engineering Mechanics; Teknisk mekanik;

    Abstract : Homogenization of alloying elements is desired during sintering of powder metallurgy components. The redistribution processes such as penetration of liquid phase into the interparticle/grain boundaries of solid particles and subsequent solid-state  diffusion of alloy element(s) in the base powder, are important for the effective homogenization of alloy element(s) during liquid phase sintering of the mixed powders.

  7. 5. Alternative reducing agents in metallurgical processes : Experimental study of thermal characterization of shredder residue material

    Author : Samira Lotfian; Noureddine Menad; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Abstract : Coal used in metallurgical processes can participate in reduction reactions to produce metals and alloys from oxides. Base metals production leads to generation of slag, which contains valuable metals that can be recovered and recycled. There are several options to treat the slag, depending on the metal content in the slag. READ MORE
