  1. 1. PGE Geochemistry and Mineralogy of Dunite, Chromitite, and Laterite Samples from the Acoje Ophiolite Block, Philippines

    University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

    Author : Michelle Dossey; [2023]
    Keywords : PGM; PGE; laterite; limonite; chromitite; dunite; platinum group minerals; platinum group elements; Acoje; Philippines;

    Abstract : Ni-laterites have the potential to become unconventional ore deposits for platinum group elements (PGE). This study was conducted to determine enrichment trends of PGE as a result of the Ni-laterization process. READ MORE

    Keywords : Canada; Yukon; silver; lead; zinc; galena; sulfosalt; sulfur isotope;

    Abstract : The Silver Hart property is a high grade silver-lead-zinc deposit consisting of polymetallic vein style, manto (carbonate replacement) style, and skarn type mineralization. Host rock consists of calcareous and non-calcareous sediments of the Cassiar Platform, mainly biotite schists, limestone units, and the monzogranite unit of the Cassiar Batholith. READ MORE

  4. 3. 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

    Abstract : The escalating demand for metals driven by advancements in renewable energy technologies and hightech products has underscored the significance of understanding and characterizing ore deposits. This study focuses on the Ertelien Ni-Cu deposit in Norway, a region rich in nickel, cobalt, and copper resources—essential components for the transition to a sustainable energy future. READ MORE

  6. 5. Character and Evolution of Ore Mineralisation in the Te-Rich Enåsen Au-Cu Deposit, Central Sweden

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Simon Pieslinger; [2023]
    Keywords : ore geology; partial melting; quenching textures; symplectite; tellurides; critical metals;

    Abstract : The Enåsen gold deposit is located in Gävleborg county in central Sweden. Mining operations at Enåsen took place from 1984 to 1991 with Au as the main target for exploitation. The deposit has been interpreted as a metamorphosed Palaeoproterozoic analogue to near-recent epithermal Au mineralisations of a high sulphidation type. READ MORE
