  1. 1. Investigating the effect of grinding method on ore beneficiation behaviour

    University essay from Luleå tekniska universitet/Mineralteknik och metallurgi

    Author : Mellisa Tanaka Mundida; [2023]
    Keywords : flotation; grinding; liberation; chalcopyrite; beneficiation; grinding method; selectivity index; VRM; Aitik ore; rodmill; particle shape;

    Abstract : 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. READ MORE

  3. 2. 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.

    Author : Oskar Bertéus; Benjamin Dobberke; [2021-07-06]
    Keywords : Sustainable Business Model; Business Model Innovation; Sustainable Development Goals; Opportunity Recognition;

    Abstract : 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. 3. A process mineralogy study of grinding characteristics for the polymetallic orebody, Lappberget Garpenberg

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

    Author : Gustav Lood Stark; [2021]
    Keywords : Automated mineralogy; autogenous milling; grinding characteristics; mineral characterization; process mineralogy geometallurgy; blending strategies; energy consumption; throughput; scanning electron microscope SEM ;

    Abstract : 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. 4. Distal Radius Fracture : – Treatment, Complications, and Risk Factors for Re-operation.

    University essay from Örebro universitet/Institutionen för medicinska vetenskaper

    Author : Alexandra Pickett; [2020]
    Keywords : Distal Radius Fracture; AO-classification; ulnar variance; plating; re-operation;

    Abstract : 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.
