  1. 11. Submarine Alteration of Seamount Rocks in the Canary Islands: Insights from Mineralogy, Trace Elements, and Stable Isotopes

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Aduragbemi Oluwatobi Sofade; [2018]
    Keywords : Canary Islands; seamounts; submarine alteration; trace elements; nannofossils; Kanarieöarna; djuphavsberg; undervattensomvandling; spårämnen; nanofossiler;

    Abstract : Seamounts play an important role in facilitating the exchange of elements between the oceanic lithosphere and the overlying seawater. This water-rock interaction is caused by circulating seawater and controls the chemical exchange in submarine and sub-seafloor rocks. READ MORE

  2. 12. 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

  3. 13. 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

  4. 14. 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

  5. 15. Geometallurgical approach to understand how the variability in mineralogy at Zinkgruvan orebodies affects the need for copper activation in the bulk rougher-scavenger flotation

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

    Author : Ivan Belo Fernandes; [2017]
    Keywords : Geometallurgy; Zinkgruvan; Zn-Pb flotation; ore variability; mineral chemistry; pyrrhotite; magnetic separation;

    Abstract : Zinkgruvan is a Pb-Zn-Ag deposit located in south-central Sweden, owned and operated by Lundin Mining. The ore is beneficiated by a collective-selective flotation circuit, recovering both galena and sphalerite in a bulk rougher-scavenger flotation stage and later on separating them into two final products.
