PhD Student (m/f/d) in situ X-ray imaging of mineral dissolution from ores in deep eutectic solvents
A member of the Helmholtz Association of German Research Centers, the HZDR employs about 1,100 people. The Center's focus is on interdisciplinary research in the areas energy, health, and matter.
The Helmholtz Institute Freiberg for Resource Technology (HIF) pursues the objective of developing innovative technologies for the economy so that mineral and metalliferous raw materials can be made available and used more efficiently and recycled in an environmentally friendly manner.
As part of the HIF, the Department of Processing, invites applications as PhD Student (m/f/d) in situ X-ray imaging of mineral dissolution from ores in deep eutectic solvents.
The position will be occupied as soon as possible, provided that funding is approved. The employment contract is limited to three years. The PhD Student (m/f/d) will be registered as a postgraduate student at the Technical University Bergakademie Freiberg. The place of work is the Helmholtz Institute Freiberg for Resource Technology (HIF).
The position is integrated in an international consortium of partners from research and industry. In collaboration with project partners, the student (m/f/d) will study the dissolution behaviour of minerals in deep eutectic solvents (DES) in order to improve the understanding of ionometallurgical dissolution processes. A unique experimental cell to be mounted in a computed micro-tomography (CT) scanner will be developed and used to study 3D changes in the solid phase over time during leaching experiments. In doing so, the volume loss of minerals can be directly imaged, enabling the direct quantification of leaching rates as a function of time, reactive surface area and mineral association and distribution. The knowledge from this project will be fed into leaching models and used to implement a pilot-scale ionometallurgical leaching process.
