Luleå University of Technology is growing rapidly with world-leading expertise in several research areas. We shape the future through innovative education and groundbreaking research results, and based on the Arctic region, we create global social benefits. Our scientific and artistic research and education are conducted in close collaboration with international, national and regional companies, public actors and leading universities. Luleå University of Technology has a total turnover of almost SEK 2.1 billion per year. We are currently 1,900 employees and have 18,700 students. In the coming years, billions of kronor will be invested in Norrbotten and Västerbotten in major projects aimed at a more sustainable society nationally as well as globally. Luleå University of Technology is involved in several of these highly topical research projects and the social transformation that follows. We have a wide range of programs to match the skills that are in demand. We hope you will help us build the sustainable businesses and societies of the future. In line with the green transition and with a view to sustainable supply of critical raw materials, our research in mineral engineering consists of three pillars: material characterization (mineralogical and particle analyses), unit operations (such as comminution and separation processes) and systems engineering approaches (modelling and simulation, geometallurgy). Experimental work (on ore and mineral processing) is carried out in our well-equipped mineral engineering laboratory with access to state-of-the-art instruments and a wide range of process equipment. In undergraduate education, we contribute to engineering programs such as Sustainable Process and Chemical Engineering, Earth Sciences Resources and Arctic Mineral Resources. Subject description Mineral Engineering deals with unit operations and processes for the preparation of solid, particulate materials, primarily ore minerals, industrial minerals and solid fuels, but also residues, recycled materials and products from the process industry. Project description We are looking for a postdoctoral fellow in mineral engineering. As a postdoc, you will be part of an established research group operating in a dynamic, international research environment to work on a new research project, enrichment of eudialyte ores. Eudialyte is a strategically important source of rare earth elements and represents a promising raw material for Europe's growing advanced materials sector. The Norra Kärr ore (in central Sweden) contains remarkable eudialyte-bearing intrusions that could form the basis for building a resilient and sustainable rare earth value chain from domestic sources. The project aims to develop and refine flotation strategies tailored for eudialyte ores of different mineralogical compositions and alterations. The postdoctoral research in this project will emphasize the design of enrichment processes, including process mineralogical characterization, selective flotation with environmentally friendly collectors, micro- and nano-bubble techniques, and controlled desliming to improve recovery. The focus will be on understanding how flotation parameters affect process selectivity and separation performance. Duties and responsibilities This postdoctoral position involves both theoretical and practical work. Most of your working time will be devoted to your own research, but you will also be expected to supervise master students and collaborate with PhD students. In addition, you will have the opportunity to contribute to the department's teaching activities at undergraduate level. A postdoctoral position involves scientific work in the form of publishing scientific articles in journals and presenting at national and international conferences. As a postdoctoral fellow, you will be expected to take significant responsibility for planning and managing your own project. Qualifications To be eligible for employment as a postdoctoral fellow, a doctoral degree in mineral engineering, natural resource engineering or equivalent is required. It is an advantage if your degree was obtained no more than three years before the closing date for applications for this position. If there are special reasons, those who have obtained a doctorate earlier may be considered, for example in the case of various types of statutory leave. When evaluating, we pay particular attention to: - Sound training in mineral engineering (theoretical knowledge and experimental experience in various enrichment methods, especially in froth flotation) - Knowledge and experience in mineralogical characterization - Quality and relevance of publications - Quality of the doctoral thesis - Communication and collaboration skills - Personal qualities relevant to research work We are looking for researchers who can work independently as well as in a team. You must have very good communication skills and be fluent in English, both spoken and written. Additional knowledge of a Scandinavian language is an advantage. Information to be provided This position is a full-time position for a period of two years. Place of employment: Luleå. Start date: as agreed but as soon as possible.
