1. 1. A process mineralogy study of grinding characteristics for the polymetallic orebody, Lappberget Garpenberg

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

   Author : Gustav Lood Stark; [2021]
   Keywords : Automated mineralogy; autogenous milling; grinding characteristics; mineral characterization; process mineralogy geometallurgy; blending strategies; energy consumption; throughput; scanning electron microscope SEM ;

   Abstract : Most of the high-grade ores have been depleted globally, thus the effective processing of the low-grade and complex ores require a comprehensive mineral characterization through the process mineralogy/ geometallurgical approaches. 30-70 % of the total energy consumption in mining comes from the comminution step in mineral processing.

3. 2. A Geometallurgical Approach Towards the Correlation Between Rock Type Mineralogy and Grindability: A case study in Aitik mine, Sweden

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

   Author : Raoul Schmitt; [2021]
   Keywords : Geometallurgy; autogenous grinding; process mineralogy; grindability test; abrasion breakage; automated mineralogy;

   Abstract : Aitik is a large copper porphyry type deposit located in northern Sweden, currently exploited at an annual rate of approximately 45Mt. The ore's exceptionally low head grade of 0.22 % Cu and varying degrees of hardness across the entire deposit pose challenges to the two fully autogenous grinding lines, each of which comprises a 22.

4. 3. 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

5. 4. 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

6. 5. 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
