Research Assistant - salary grade E13 TV-L Berliner Hochschulen

part-time employment may be possible

Working field:

An up to now unused source of critical raw materials are solidified slags from pyrometallurgical processes. In these, critical raw materials can accumulate in the form of Engineered Artificial Minerals (EnAMs). For the first time, research into the processing and use of EnAMs is being carried out on a broader scale specifically within the PP 2315 ( Thereby one focus of PP 2315 is the aspect, that in order to make critical raw materials from EnAMs accessible, they have to be broken down and separated by crushing.

The project "Numerical investigation of the liberation of critical raw materials in the form of Engineered Artificial Minerals (EnAMs) from tailored solidified slag phases by DEM-based comminution modelling" and the position advertised here is dedicated to the latter named aspect.

The aim is to use the DEM (Discrete Element Method) to contribute to the prediction of EnAM liberation from slags. This requires that both comminution in terms of size reduction and liberation are to be represented. For this purpose, a modeling framework is to be created that covers various loading conditions from static to dynamic. The modeling framework is calibrated to at least one EnAM-containing slag system, as is taken into account in PP 2315. By applying it to comminution devices on laboratory scale and benchmarking with experimental data, with regard to size distributions and degrees of liberation, it is verified that the DEM can be applied to complex slag systems that contain EnAMs. This makes it possible to use the predictive capabilities of the DEM in order to analyze, as a second step, the optimal interconnection of comminution processes for the EnAM liberation from slags.
