  4. 2. Computational methods and strategies for geometallurgy

    Author : Pierre-Henri Koch; Jan Rosenkranz; Eric Pirard; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geometallurgy; process simulation; minerals; machine learning; textures; decision-making; Mineral Processing; Mineralteknik;

    Abstract : At the interface of geology and mineral processing, geometallurgy is a powerful tool for enhancingresource efficiency. A spatial model that represents the ore body in terms ofmineralogyand physical properties is combined with a process model that describes the concentrationprocess. READ MORE

  5. 3. Exploiting reciprocal space : Electron diffraction, textures and precession

    Author : Peter Oleynikov; Sven Hovmöller; Xiaodong Zou; Jean-Paul Morniroli; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; electron crystallography; electron diffraction; texture patterns; precession electron diffraction; Inorganic chemistry; Oorganisk kemi;

    Abstract : Electron crystallography emerges as a new tool for accurate structure determination of very small crystals. In order to exploit the full potential of electron diffraction, the methods for data acquisition and processing have to be developed towards the high standards of X-ray crystallography. READ MORE

  6. 4. Quantum Hall Skyrmions and Edge Spin Textures

    Author : Kennet Lejnell; Carlos Tejedor; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical Physics; teoretisk fysik;

    Abstract : In the quantum Hall effect, new and surprising phenomena continue to be uncovered. For example, in quantum Hall ferromagnets Skyrmions have been observed---these quasiparticles carry electric charge and a large spin. The spin is ordered in a beautiful wavelike pattern, as shown on the front of this thesis. READ MORE

  7. 5. Metamorphic zircon formation in gabbroic rocks – the tale of microtextures

    Author : Victoria Beckman; Berggrundsgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Zircon formation; metamorphism; prograde; gabbr; zircon; baddeleyite; zircon; baddeleyite; metamorphic; prograde; zircon textures;

    Abstract : Dating of metamorphic events is crucial for the understanding and reconstruction of large-scale geological processes such as orogenesis. Zircon is one of the most commonly used minerals for dating of igneous and metamorphic events. Zircon incorporates uranium and excludes lead during crystallization, and with time the uranium decays to lead. READ MORE
