  1. 1. Textural characterization of gold in the Björkdal gold deposit, northern Sweden.

    University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

    Author : Fredrik Westberg; [2021]
    Keywords : Björkdal gold deposit; gold; gold-telluride; SEM; mineral association; grain size; geometallurgy;

    Abstract : The Björkdal gold deposit is located in the eastern part of the Skellefte district, northern Sweden. Twenty thin sections from four production areas in the open pit and four drifts from the underground mine were analysed for mineral association and grain size distribution of gold. READ MORE

    University essay from Luleå tekniska universitet/Mineralteknik och metallurgi

    Author : Juan Sebastian Guiral Vega; [2018]
    Keywords : Lithium; Image Analysis; Spodumene; Pegmatite; Hyperspectral; Geometallurgy; Machine learning; Mineralogy; characterization; Mineral mapping; Texture; Scanning electron microscopy; SEM; Mineral Processing; Kaustinen; Keliber; Lithium deposit; Geometalurgia; procesamiento mineral; litio; espodumena; pegmatita; machine learning; procesamiento mineral;

    Abstract : Lithium represents one of the strategic elements for the rest of the 21st century due to its increasing demand in technological applications. Therefore, new efforts should be focused on the optimization of mineral characterization processes, which link the ore properties with its behaviour during downstream processes. READ MORE

  5. 4. Characterization of the Hydrothermal Alteration around the Björkdal Au Deposit, Skellefte District, Sweden

    University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

    Author : Madeleine Erneholm; [2017]
    Keywords : Gold Ore; Mine; Skellefte District; Sweden; Quartz Lode; Hydrothermal Alteration; Petrography; Lithogeochemistry; Intrusion-related Gold;

    Abstract : Sixteen samples from 8 locations within and surrounding the Björkdal mine area in northern Sweden were chosen in order to reevaluate and characterize previous interpretations of the lithology and hydrothermal alteration. Geochemical analysis by ICP-MS was made in order to chemically classify the lithology of the area and petrological studies were made by study of thin sections and core logging. READ MORE

  6. 5. Classification of Drill Core Textures for Process Simulation in Geometallurgy : Aitik Mine, Sweden

    University essay from Luleå tekniska universitet/Mineralteknik och metallurgi

    Author : Glacialle Tiu; [2017]
    Keywords : ore texture; texture classification; Machine Learning; drill core photography; scanning electron microscope; X-ray microtomography; mineral mapping; stereology;

    Abstract : This thesis study employs textural classification techniques applied to four different data groups: (1) visible light photography, (2) high-resolution drill core line scan imaging (3) scanning electron microscopy backscattered electron (SEM-BSE) images, and (4) 3D data from X-ray microtomography (μXCT). Eleven textural classes from Aitik ores were identified and characterized. READ MORE
