  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

  2. 2. Textural and Mineralogical Characterization of Li-pegmatite Deposit: Using Microanalytical and Image Analysis to Link Micro and Macro Properties of Spodumene in Drill Cores. : Keliber Lithium Project, Finland.

    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

  3. 3. Particle tracking in geometallurgical testing for Leveäniemi Iron ore, Sweden

    University essay from Luleå tekniska universitet/Mineralteknik och metallurgi

    Author : Efraín Cárdenas; [2017]
    Keywords : Geometallurgy; Process mineralogy; Particle tracking; Leveäniemi; Mass balance; Iron ore; HSC;

    Abstract : In a particle based geometallurgical model, the behavior of the particles can be used for forecast the products and quantify the performance of the different ore types within a deposit. The particle tracking is an algorithm developed by Lamberg and Vianna 2007 whose aim is to balance the liberation data in a mineral processing circuit composed by several processing units. READ MORE

  4. 4. A Geometallurgical Forecast Modelfor Predicting Concentrate Quality in WLIMS Process for Leveäniemi Ore

    University essay from Luleå tekniska universitet/Mineralteknik och metallurgi

    Author : Kartikay Singh; [2017]
    Keywords : Mineral processing; geometallurgy; modelling; Davis Tube; WLIMS; LKAB; Leveäniemi;

    Abstract : Previous studies have suggested that Davis tube (DT) experiment can used to study wet low intensitymagnetic separation (WLIMS) for magnetic iron ores. But DT process has never been used to mapWLIMS process, specifically in a geometallurgical framework. READ MORE

  5. 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
