  1. 26. The Unexplored Earth : Inspiring the future of mineral exploration

    University essay from Umeå universitet/Designhögskolan vid Umeå universitet

    Author : Alexandre De Bastiani; [2020]
    Keywords : design; concept; epiroc; mineral exploration;

    Abstract : Very much like the great navigations in the 14th century or the space programs, exploring remote parts of our planet is a dangerous, challenging, and unknown endeavor that drives human beings. We not only do it to find resources but also for the sake of science, looking for shreds of evidence of a past that we only speculate. READ MORE

  3. 27. Factors controlling the sorption of Cs, Ni and U in soil : A statistical analysis with experimental sorption data of caesium, nickel and uranium in soils from the Laxemar area

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Emilia Johansson; [2020]
    Keywords : correlation analysis; Kd values; partition coefficient; Pearson correlation; radionuclide; soil; sorption;

    Abstract : In the fall of 2006, soils from three small valleys in the Laxemar/Oskarshamn area were sampled. A total of eight composite samples were characterized for a number of soil parameters that are important for geochemical sorption and were later also used in batch sorption experiments. READ MORE

  4. 28. Identifying Quaternary Climate Change with XRF Analysis on Loess From South-Western England

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Pelle Kronborg; [2020]
    Keywords : loess; XRF; weathering index; England; Lowland Point; Porth Cressa; Quaternary; löss; XRF; vittrings index; kvartär; England; Lowland Point; Porth Cressa;

    Abstract : Huge changes in climate occurred at the end of the last Quaternary glaciation. The end of this glaciation corresponds with the end of Pleistocene with its repeated glacial cycles and the start of the current geological epoch, the Holocene interglacial. READ MORE

  5. 29. Geochemical and Mineralogical Comparison of XRT-XRF Scanning Technology Versus Traditional Analysis of Drill Core from the Assarel Porphyry Copper-Gold Deposit (Panagyurishte District, Bulgaria)

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Diego Delgado Yanez; [2020]
    Keywords : Assarel porphyry copper; GeoCore X10; Sustainable mining; XRT XRF; mineral characterization; geochemical characterization; X-MINE Project;

    Abstract : Ongoing, environmental and economic matters related to mining sustainability and its impacts are leading to the search for new ways to asses and extract commodities more efficiently. A key aspect in the shift to more sustainable mining is the rapid, digital characterization of orebody mineralogy and geochemistry to help optimize the extractive process. READ MORE

  6. 30. Mineralogical and Geochemical Study of Acid Mine Drainage from 100 Years of Coal Mining in Svalbard (78° N)

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

    Author : Andreas Rehn; [2020]
    Keywords : Acid rock drainage; Acid mine drainage; coal mine waste; Pyrite; Arctic; Svalbard; Spitzbergen;

    Abstract : Waste rock piles from coal mining of tertiary bituminous coal in Longyearbyen, Svalbard, show sulfide oxidation and subsequent acid mine drainage (AMD) production. The aim was to establish deeper understanding of AMD prediction based on Mineralogy and Geochemistry of coal and AMD samples. READ MORE
