  1. 1. Calculating the combined elemental composition of spodumene using La_ICP_MS in thin_sections samples from Europe.

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Maximilian Körtge; [2023]
    Nyckelord :Lithium minerals; Spodumene; Trace-elements; La-ICP-MS; Mineral processing; Geochemistry;

    Sammanfattning : The study gives a broad background to understand the high demand of lithium batteries in the coming years, especially in Europe. The goal of the study is to use La-ICP-MS to analyse spodumene samples from different lithium deposits in Europe to get a better knowledge of the contents of trace elements in spodumene. LÄS MER

  3. 2. The effect of recycling and processing routes on recrystallization in a secondary 3xxx aluminium alloy

    Master-uppsats, Jönköping University/JTH, Material och tillverkning

    Författare :Anton Rolseth; [2023]
    Nyckelord :Aluminium alloys; sheet metal forming; grain boundary segregation; recrystallization; Zener pinning; casting; rolling;

    Sammanfattning : Aluminium alloys have the possibility to be infinitely recycled. By only generating 5% of the emissions compared to primary aluminium, great CO2 savings can be made. One of the issues in manufacturing components entirely from post-consumer scrap is the presence of trace elements and impurities. Such elements can be Fe, Cu, Cr, P and Pb. LÄS MER

    Nyckelord :;

    Sammanfattning : To consider the climate and strive to reduce greenhouse gas emissions is a current issue in today's society. The outer wall hybrid sandwich wall is a new, more environmentally friendly wall type that is being researched for use in the market. LÄS MER

  5. 4. Investigating the potential correlations between metal and metalloid concentrations and soil color : A Minor Field Study on the island province of Marinduque, Philippines

    Kandidat-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Ivana Pia Saric Söderholm; Erik Readwin; [2023]
    Nyckelord :Marinduque; Metal and Metalloid; Nix Pro 2 Color Sensor; Philippines; Soil color; X-Ray Fluorescence XRF ; Filippinerna; Jordfärg; Marinduque; Metall och Metalloid; Nix Pro 2 Color Sensor; Röntgenfluorescens XRF ;

    Sammanfattning : This study was carried out as a bachelor's thesis at KTH Royal Institute of Technology during the spring of 2023, investigating the correlation between the color with the concentration of various metal and metalloids (MMs) in the soil of Marinduque, The Philippines. With a history of mineral exploitation, notably copper and gold, the island has faced persistent environmental challenges, exemplified by the catastrophic waste spills in 1993 and 1996 that contaminated the Boac and Mogpog Rivers.
