2. 1. Bringing predictability into a geometallurgical program : An iron ore case study

   Author : Viktor Lishchuk; Bertil Pålsson; Cecilia Lund; Pertti Lamberg; Jennifer Broadhurst; Luleå tekniska universitet; []
   Keywords : 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;

   Abstract : 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. READ MORE

4. 2. Mineralogical, chemical and textural properties of the Malmberget iron deposit : a process mineralogically characterisation

   Author : Cecilia Lund; Luleå tekniska universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Malmgeologi; Ore Geology;

   Abstract : This thesis combine two different but closely connected disciplines in a mining process to each other, ore geology and process mineralogy by studying mineralogical-textural features of the ore and the ore concentrate in an apatite iron ore deposit in Malmberget, Sweden. Apatite iron ore deposits (Kiruna type) exist in a few places around the world and the two most important deposits are mined by LKAB at Kiruna and Malmberget. READ MORE

5. 3. Towards reliable seismic hazard assessment in underground mines

   Author : Wille Törnman; Savka Dineva; Jesper Martinsson; Adam Jonsson; Björn Lund; Luleå tekniska universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

   Abstract : Seismic hazard is used for national, regional, and local level to ensure safe constructions in specific areas. In the mining industry this information is valuable e.g. to  design infrastructure or rock support, to reduce the risk of rock burst and to minimise the risk of locating personnel in hazardous areas.

6. 4. When Employees Leap to Self-Employment

   Author : Frederik Witte; Företagsekonomiska institutionen; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; self-employment entry; occupational choice; idea creation; occupation; laboratory experiment; panel data; survival analysis; data mining; model; entrepreneurship;

   Abstract : The dissertation studies the determinants of self-employment entry through an economics of entrepreneurship lens, and examines two sources of data: 7 years of employer--employee matched panel data and a laboratory experiment. The results suggest that employees are more likely to take the leap to self-employment when they have their own business idea, and are employed in occupations with high wage variance. READ MORE

7. 5. Use of data mining and artificial intelligence to derive public health evidence from large datasets

   Author : Hugo Fitipaldi; Genetisk och molekylär epidemiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; artificial Intelligence; data mining; genome-wide association studies; covid-19;

   Abstract : This thesis explores the use of data mining and AI-tailored frameworks for extracting public health evidence from large health datasets. The research presented in this thesis demonstrates the potential of these tools for automating and simplifying the data mining process, and for providing valuable insights into various public health issues.
