  1. 1. Recovery of Cobalt and Copper from Zambia Slag via Sulphidisation with Gypsum

    University essay from KTH/Materialvetenskap

    Author : Lloyd Masuzyo Mseteka; [2021]
    Keywords : ;

    Abstract : The main objective of this research was to recover copper and cobalt from slags coming from copper processing on the Copperbelt province of Zambia. Pyrometallurgical processing of copper sulphide concentrate generates huge tonnes of slag wastes. READ MORE

  2. 2. 2D Reflection Seismic Imaging of Sparse 3D Data in the Zinkgruvan Mine, Central Sweden

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Maryam Abbasian; [2021]
    Keywords : 2D crooked-line; reflection seismic; sparse 3D; mineralization; Zinkgruvan; 2D modellering; reflektionsseismik; mineralisering; Zinkgruvan;

    Abstract : Zinkgruvan mining area in the southern Bergslagen mineral district of central Sweden holds over 30 million tons of massive sulphide mineralization. The ever-increasing global demand for mineral/metal resources, together with metal consumption growth especially for high-tech purposes has made the exploration of these resources of particular importance.

  3. 3. U-Pb age constraints on the host rocks of the Barsele Norra Volcanogenic Massive Sulphide deposit, northern Sweden

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

    Author : Maria Sandlund; [2021]
    Keywords : Geochronology; Skellefte district; Barsele; VMS; LA-ICP-MS; SEM;

    Abstract : The Barsele area is located in the "Gold Line", southwest of the volcanogenic massive sulphide (VMS) Skellefte district which hosts more than 85 known VMS-deposits where some are gold-bearing. The Barsele area consists of the Central, Avan and Skiråsen intrusion hosted gold deposits, the Norra gold-bearing VMS-deposit and the Risberget zone. READ MORE

  4. 4. Evaluation of 25 MHz Ultrasonic Testing for Detection of Non-Metallic Inclusions in Steel

    University essay from KTH/Materialvetenskap

    Author : Henrietta Isaksson; [2021]
    Keywords : Ultrasonic Testing; High Frequency Ultrasonic Testing; Quantification of inclusions; Fatigue Testing; Ultraljudstestning; Högfrekvent ultraljudstestning; Kvantifiering av inneslutningar; Utmattningstestning;

    Abstract : Quantification of inclusions is important since it is correlated to the steel’s fatigue properties. One method that could be further developed for detection of inclusions in steel is ultrasonic testing (UST). READ MORE

  5. 5. Partial hydrodeoxygenation of a heavy bio-based oil fraction : (A technical feasibility study)

    University essay from KTH/Kemiteknik

    Author : Akshay Menon; [2020]
    Keywords : Hydrodeoxygenation; Tall oil pitch; oxygen removal; sulphidation; catalyst;

    Abstract : This report is intended to provide the reader with an extensive background information on hydrode oxygenation (HDO) of Tall Oil Pitch (TOP), combined with results from chemical property analyses of the same. Firstly, the importance of hydrogenation and oxygen removal for a biomass-based feed material is highlighted. READ MORE
