2. 1. 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

   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

6. 4. Experimental and modelling studies of the thermophysical and thermochemical properties of some slag systems

   Author : Lijun Wang; Seshadri Seetharaman; Kuo-Chih Chou; Miyuki Hayashi; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Teknisk materialvetenskap;

   Abstract : In order to optimize the metallurgical processes it is necessary to improve the understandings of the industrial slag properties, which include thermophysical and thermochemical properties. In the present study Mass Triangle Model was applied to predict these properties. READ MORE
