    Abstract : Mining has been and still is an important industry in Sweden, it has strongly contributed to the standard of living we have today. Extraction of ore began in the 12th century, but did not come about frequently until the 16th century, which is often seen as the starting age for ore processing and metal extraction. READ MORE

  4. 2. Ageing behaviour of steel slags in landfill liners

    Author : Silvia Diener; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Waste Science and Technology; Avfallsteknik;

    Abstract : Steel slags are by-products of the steelmaking process. To avoid unnecessary disposal, e.g. into landfill, their chemical and physical properties should be exploited to support alternative uses. READ MORE

  5. 3. Experimental studies to overcome the recycling barriers of stainless-steel and BOF slags

    Author : Mattia De Colle; Pär Jönsson; Andrey Karasev; Muxing Guo; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stainless steel; slag; recycling; sustainability; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : This thesis presents several studies aimed at improving the recycling of steel slag. The studies are based on a first evaluation of the state-of-the-artof the recycling applications both with respect to their possibilities and limitations. READ MORE

  6. 4. A Study on Vanadium Extraction from Fe-V-P Melts Derived from Primary and Secondary Sources

    Author : Mikael Lindvall; Du Sichen; Christiaan Pistorius; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vanadium; V; V2O5; V2O3; ferrovanadium; vanadiferous; titaniferous; titanomagnetites; magnetite; spinel; slag; experimental; free; spinel; converter; LD; BOF; solubility; equilibrium; selective; oxidation; hibonite; karelianite; Al2O3; CaO; SiO2; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : Vanadium extraction methods were developed for iron-vanadium-phosphorus (Fe-V-P) melts derived from processing of V-bearing titanomagnetites and steel slags. Studies on phase relationships of V slags were carried out to provide important understanding of the extraction processes. READ MORE
