Phd Student in Mineral Processing

Updated: 4 months ago


We are looking for a PhD student in Mineral Processing. The student will join an established research group to work with a research project on novel approaches to efficient comminution and separation, involving new applications for existing mill types, process designs for staged comminution and concentration, pre-weakening treatments. The project is funded within the Kolarctic Cross Border Cooperation SEESIMA – “Supporting environmental; economic and social impact of mining activities” run at Luleå University of Technology together with academic partners from Finland, Norway and Russia.


Mineral Processing deals with the unit operations and processes for treating particulate solids, primarily metal ores, industrial minerals and solid fuels, but also residues and recyclable waste material as well as products from the processing industry.


Grinding is not only the most energy-demanding process step in mineral beneficiation. It is also crucial for the efficiency of the subsequent concentration processes. In order to adjust the grinding process to both, ore feed properties and necessary separation process conditions, tests with different mills (such as stirred media mills and tumbling mills) and grinding environments (dry or wet) will be conducted and evaluated by complementing separation test works.


A position as a PhD student involves both theoretical and experimental work. The PhD student is trained in scientific work in terms of publishing scientific journal articles and papers to national and international conferences. A PhD student even takes mandatory and elective courses. Besides that, you can get the opportunity to try out teaching. As a researcher, you work as a neutral part in many contexts, which gives a great opportunity to learn how to run challenging development projects.

The work mainly includes the following tasks:

  • Planning and conduct of experimental tests (comminution and separation test work, mineralogical characterization and particle analyses).
  • Optimizing energy consumption and grind size for mineral liberation pulp chemistry
  • Optimizing separation processes for differently ground samples
  • Evaluation of effects of different grinding environments on the downstream processes
  • Reporting within the project

 The PhD studies are 4 year, fulltime. Administration and/or lecturing of maximum 20% may be added.


Eligible candidates for the position must have a master degree of at least 120 ECTS in mineral processing, natural resource engineering or other relevant programmes. The candidate is expected to have a solid education within mineral processing, with theoretical knowledge as well as practical experience of various beneficiation methods. Knowledge in particle analyses and mineralogical characterization are seen as a merit. The applicant must have good English language proficiency (oral and wrtitten). For additional information on the specific PhD programme please visit General syllabus - The Board of the Faculty of Science and Technology


At Luleå University of Technology, the PhD students will normally conclude a licentiate degree halfway through their studies. PhD students will be offered a position for 4 to maximum 5 years (if teaching or other departmental work of max. 20% is included in the position). Regulations can be found in Högskoleförordningen 5 kap §§ 1-7. Local guidelines for salary exist. Entrance to the position according to agreement with Luleå University of Technology.
