  1. 1. Petrography, alteration and structure of the Bronäs Zn-Pb-Ag deposits, Bergslagen, Sweden

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Tom Turner; [2020]
    Keywords : Bronäs; Sala;

    Abstract : This report aims to characterize the alteration styles and mineralization of the Zn-Pb-Ag Bronäs deposit, in the Sala area of the Bergslagen mining district, Sweden.  It presents data collected through 237m of lithological logging and subsequent lithogeochemical data, which, coupled with thin section and SEM analysis has led to the first geological descriptions of the rocks in the deposit.

  2. 2. Some Study related to Refractory Waste Management in Sweden : A move towards a greener and sustainable Swedish steel industry

    University essay from KTH/Materialvetenskap

    Author : Surbhi Shivaji Jogdand; [2020]
    Keywords : Refractory waste; Swedish steel producers; Recyclers; MgO-C bricks; Fines; MgO; Carbon elimination; Agriculture industry; Eldfast avfall; svenska stålproducenter; Återvinnare; MgO-C-tegel; Böter; MgO; Koleliminering; Jordbruksindustri.;

    Abstract : Decades  ago,  1  ton  of  steel  required  80  kg  of  refractory  material.  While  the  scenario  has completely changed over the years. Today, 1 ton of steel needs approximately 11 kg of refractory material   depending   on   the   steelworks. READ MORE

  3. 3. Investigation of Cu and Zn interactions with ilmenite during waste incineration

    University essay from Chalmers tekniska högskola / Institutionen för kemi och kemiteknik

    Author : Elin Borgman; [2020]
    Keywords : FactSage; copper; zinc; major ash elements;

    Abstract : In 2018, approximately 2.01 billion tons of waste was generated in the world. By 2050, this number is expected to increase drastically to 3.40 billion tons of waste annually as lower income countries develop and the world population increases (Kaz, Yao, BhadaTata, & Van-Woerden, 2018).

  4. 4. Effect of iron redox state on crystallization behaviour of Fayalite slags

    University essay from KTH/Materialvetenskap

    Author : Paolo Mai; [2020]
    Keywords : Copper smelting; Slag; Magnesium Oxide; Iron redox equilibria; Optical basicity; Raman spectroscopy.; Smältning av koppar; Slagg; Magnesiumoxid; Järnredoxjämvikt; Optisk basicitet; Ramanspektroskopi.;

    Abstract : In the copper smelting processes, the viscosity of the matte and the slag is an important factor for establishing efficiency. Impurities in the concentrates affect the viscosity not only by changing the melt structure but also by promoting precipitation of solid phase which sharply rises it. READ MORE

  5. 5. Design and Simulation of Terahertz Antenna for Spintronic Applications

    University essay from Uppsala universitet/Institutionen för materialvetenskap; Uppsala universitet/Institutionen för materialvetenskap; Uppsala universitet/Institutionen för materialvetenskap; Uppsala universitet/Institutionen för materialvetenskap

    Author : Nils Eivarsson; Malin Bohman; Emil Grosfilley; Axel Lundberg; [2020]
    Keywords : spintronics; terahertz; THz; antenna; simulation; COMSOL multiphysics;

    Abstract : Spintronics is a spin-electronic field where the electron spinangular momentum, in conjunction with charge, is used to read andwrite information in magnetic sensors and logic circuits, e.g. hard disk drive (HDD), magnetic random access memory (MRAM) and broadband TeraHertz (THz) emitters.
