1. Investigating the effect of grinding method on ore beneficiation behaviour
Master-uppsats, Luleå tekniska universitet/Mineralteknik och metallurgiSammanfattning : Commodity projection studies anticipate an exponential increase in copper demand and decreasein mill grade of deposits currently exploited globally. Most of this demand is driven by theindispensable use of copper in electrification and currently, the growing demand in the contextof the green transition. LÄS MER
2. Kalibrering av krossmodeller genom laborativa tester och weibull analys
Kandidat-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomiSammanfattning : Today’s society relies strongly on the mining industry. In this industry, crushing is an essential step of the process of extracting materials. Crushing is a part of the comminution process, where stones are broken down into smaller fragments. One of the key products for this process is the cone crusher. LÄS MER
3. Sustainability as an opportunity: Value creation for innovative ventures through proactively tackling environmental and social issues. A study on Librixer AB about reducing water pollution by recycling unused pharmaceuticals.
Master-uppsats, Göteborgs universitet/Graduate SchoolSammanfattning : This thesis argues that Sustainable Business Model Innovation should be considered an essential process for small- and medium-sized enterprises to create value. In order to establish a sustainable value proposition, the researchers propose that social, economic and environmental attributes have to be considered from the start of a Business Model Innovation process and that social and environmental aspects cannot simply be added to an existing Business Model.

4. A process mineralogy study of grinding characteristics for the polymetallic orebody, Lappberget Garpenberg
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : Most of the high-grade ores have been depleted globally, thus the effective processing of the low-grade and complex ores require a comprehensive mineral characterization through the process mineralogy/ geometallurgical approaches. 30-70 % of the total energy consumption in mining comes from the comminution step in mineral processing.

5. Distal Radius Fracture : – Treatment, Complications, and Risk Factors for Re-operation.
Master-uppsats, Örebro universitet/Institutionen för medicinska vetenskaperSammanfattning : Introduction: Distal radius fractures (DRF’s) are one of the most common types of fractures,especially in elderly women. In the last decade, there has been a shift in the treatment methodemployed for DRF’s from the traditional non-operative to an operative method using plates andscrews even though there is no evidence to suggest that this method has superior outcomes.
