1. 1. Computational methods and strategies for geometallurgy

   Författare :Pierre-Henri Koch; Jan Rosenkranz; Eric Pirard; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geometallurgy; process simulation; minerals; machine learning; textures; decision-making; Mineral Processing; Mineralteknik;

   Sammanfattning : At the interface of geology and mineral processing, geometallurgy is a powerful tool for enhancingresource efficiency. A spatial model that represents the ore body in terms ofmineralogyand physical properties is combined with a process model that describes the concentrationprocess. LÄS MER

3. 2. X-ray microcomputed tomography (µCT) as a potential tool in Geometallurgy

   Författare :Pratama Istiadi Guntoro; Yousef Ghorbani; Jan Rosenkranz; Matthew Pankhurst; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; X-ray microcomputed tomography; geometallurgy; automated mineralogy; ore characterization; Mineral Processing; Mineralteknik;

   Sammanfattning : In recent years, automated mineralogy has become an essential tool in geometallurgy. Automated mineralogical tools allow the acquisition of mineralogical and liberation data of ore particles in a sample. These particle data can then be used further for particle-based mineral processing simulation in the context of geometallurgy. LÄS MER

4. 3. X-ray microcomputed tomography (µCT) as a potential tool in particle-based geometallurgy

   Författare :Pratama Istiadi Guntoro; Yousef Ghorbani; Jan Rosenkranz; Veerle Cnudde; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; X-ray microcomputed tomography; Mineralogy; Texture; Liberation; Geometallurgy; Mineral Processing; Mineralteknik;

   Sammanfattning : In recent years, automated mineralogy has become an essential tool in geometallurgy. Automated mineralogical tools allows the acquisition of mineralogical, textural, and liberation information of ore samples. Such information is essential in the context of geometallurgy where it is needed for estimating the process response of the ores. LÄS MER

5. 4. Bringing predictability into a geometallurgical program : An iron ore case study

   Författare :Viktor Lishchuk; Bertil Pålsson; Cecilia Lund; Pertti Lamberg; Jennifer Broadhurst; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additivity; Apatite iron ore; AIO; Block model; Change of support; Classification; Data integration; DT; Feed quality; Geometallurgical program; Geometallurgy; Iron ore; Iron recovery; Leveäniemi; Liberation; Machine learning; Magnetic separation; Malmberget; Mineralogical approach; Mineralogy; Prediction; Proxies; Proxies approach; Sampling; Simulation; Synthetic ore body; Traditional approach; WLIMS; Mineral Processing; Mineralteknik;

   Sammanfattning : The risks of starting, operating and closing mining projects have become higher than ever. In order to stay ahead of the competition, mining companies have to manage various risks: technical, environmental, legal, regulatory, political, cyber, financial and social. Some of these can be mitigated with the help of geometallurgy. LÄS MER

7. 5. Development of a geometallurgical framework for iron ores - A mineralogical approach to particle-based modeling

   Författare :Mehdi Parian; Pertti Lamberg; Jan Rosenkranz; Julie Hunt; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geometallurgy; process simulation; breakage characterization; ore texture; iron ore; modal mineralogy;

   Sammanfattning : The demands for efficient utilization of ore bodies and proper risk management in the mining industry have resulted in a new cross-disciplinary subject called geometallurgy. Geometallurgy connects geological, mineral processing and subsequent downstream processing information together to provide a comprehensive model to be used in production planning and management.
