Congratulations Dr. Solem
News
Dr. Cathrine Kyung Won Solem successfully defended her thesis November17th. The topic of Cathrine’s presentation at the trial lecture was “Use of Ionic Liquid Solvents for Metal Recovery”. The trial lecture was followed by an excellent presentation of her PhD thesis “Parametric Study of Molten Aluminium Oxidation in Relation to Dross Formation at Laboratory and Industrial Scale”.
Aluminium (Al) white dross, classified as a hazardous waste, is a heterogeneous mixture of metallic Al, oxides, and non-metallic compounds (NMC) originating from the primary production route of Al. Over the past few decades, a significant number of studies have been performed on topics related to molten Al oxidation. However, the formation mechanisms are still not fully understood, nor how to inhibit the oxidation. The overall scientific outcome of Cathrine’s work has therefore been to systematically determine the extent and rate of molten Al oxidation at the laboratory scale and dross formation at the industrial scale.
Cathrine has done her PhD work in the SFI Metal Production research domain “Recycling and refining" and Professor Ragnhild Aune has been the candidate’s supervisor. Professor Gabriella Tranell, Department of Materials Science and Engineering has been the candidate’s co-supervisor and Process Engineer M.Sc. Egil Solberg, Alcoa Norway has been the candidate’s supporting supervisor.
The assessment committee has been
- Prof. Dr.-Ing. Georg Rombach, Hydro Aluminium Metal, Germany
- Dr.-Ing. Bjørn Rønning, Alcoa Norway ANS, Norway
- Professor Merete Tangstad, Department of Materials Science and Engineering, NTNU
Cathrine has now started as a research scientist at SINTEF Industry, Department of Metal Production and Processing. We wish her good luck with her future endeavors!
Tizir receives 261 mill NOK from ENOVA to substitute fossile reductants with hydrogen
Congratulations to Tizir and KPN Reduced CO2 with the ENOVA funding to this important and ambitious project!
KPN Reduced CO2 is investigating the possibility to substitute fossile reductants with hydrogen in metallurgical processes including ilmenite production. This is now one step closer to industrialisation. The Norwegian ilmenite upgrader, TiZir ,one of the partners i KPN Reduced CO2 have now received 261 mill. NOK in support from ENOVA to build a pilot and demonstration plant for pretreatment of ilmenite by hydrogen.
Funding from RCN to strategically important infrastructure
SINTEF and NTNU have received funding from the Research Council for laboratory equipment related to Metal Production and Recycling. The equipment will enable advanced research in both pyro-, hydro- and electrochemical production.
The primary objective of the investment is to provide laboratory equipment supporting research in the transition to green, circular and sustainable metallurgy. SINTEF, with Dr Arne Petter Ratvik is the project owner and Professor Gabriella Tranell, co-director at SFI Metal Production, is leading the project from the NTNU side.
-We are very pleased with the awards from the Research Council. With this funding we are one step closer to transition to green, circular and sustainable metallurgy! The proposed infrastructure will expand upon existing infrastructure at NTNU and SINTEF.
New book: Principles of Metal Refining and Recycling
Congratulations to SFI research area leader Anne Kvithyld with the publication of the book Principles of Metal Refining and Recycling. The book provides a self-contained introduction to the field of purification and recycling of metals.
The scientific principles in the treatment of the various metals are the same. The importance of using a clean and properly alloyed metal is described in detail. The text covers thermodynamics, physical and transport properties, mixing, mass transfer and numerical models. It describes methods for removal of dissolved impurity elements, particles, and inclusions. It considers important aspects of the solidification process, remelting and adding of alloys. Recycling, future challenges and specific processes for each metal are discussed in detail.
Authors are Thorvald Abel Engh (NTNU), Geoffrey Sigworth (GKS engineering) and Anne Kvithyld (SINTEF), and the work has been partly funded by SFI Metal Production. The book is a greatly extended update of the 1992 book Principles of Metal Refining by T. A. Engh. It includes in particular the subjects of metal recycling, ferrous and non-ferrous metal refining, and metalloids like silicon.
New Elkem project aims to eliminate CO2 emissions from silicon production
The Research Council of Norway has granted Elkem NOK 16 million to develop a new concept for silicon production where all direct CO2 emissions are eliminated. This may become a game changer for the global silicon industry. Elkem already uses 83% renewable electricity in its operations and aims to be part of the solution to combat climate change. Silicon is a critical material for digital technologies and the green transition.
The project will run from 2022-2024. Elkem is project owner and Aasgeir Valderhaug is project manager. The Norwegian R&D institutes SINTEF and NORCE, and the pilot test centre Future Materials, will be research partners. Senior research scientist Eli Ringdalen participates in the project from SFI Metal Production.
Successful SFI Autumn Meeting November 2nd-3rd
The SFI Metal Production autumn meeting was held in Trondheim November 2-3. Due to the corona virus situation, we have not been able to organize physical consortium meetings the last two years. This time we could invite to a hybrid meeting, and about 50 participants from industry and academia met physically at Royal Garden Hotel. In addition 40 participants attended the meeting online.
Successful INFACON Conference
The 16th International Ferro-alloy Congress – INFACON XVI - was arranged as a digital conference on the 27th to 29th September from Trondheim. The intention of INFACON is to stimulate technical interchange on all aspects of silicon/ferroalloy production. The vision for the three-day conference was "CO2 free ferroalloy production". The presentations reflected the vision with a major focus on decreasing CO2 emissions, clean technologies, recycling including energy efficiency, modelling, emissions (reduce the PAH exposure risk etc.) and Markets.
Elkem Award to Professor Gabriella Tranell
Congratulations to Professor Gabriella Tranell for receiving the special award from Elkems Research Fund. The winner of the award was presented 28 September, 2021 at the opening of the INFACON XVI conference. Tranell receives the award because of her broad research and contribution to the Ferrosilicon/Silicon industry.
Congratulations Dr. Lunnan Bjørnstad
