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 geovetenskaperAbstract : 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

12. Particle tracking in geometallurgical testing for Leveäniemi Iron ore, Sweden
University essay from Luleå tekniska universitet/Mineralteknik och metallurgiAbstract : 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

13. A Geometallurgical Forecast Modelfor Predicting Concentrate Quality in WLIMS Process for Leveäniemi Ore
University essay from Luleå tekniska universitet/Mineralteknik och metallurgiAbstract : 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

14. Classification of Drill Core Textures for Process Simulation in Geometallurgy : Aitik Mine, Sweden
University essay from Luleå tekniska universitet/Mineralteknik och metallurgiAbstract : 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

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 naturresurserAbstract : 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.
