The Department of Modelling and Evaluation is looking for a PhD Student (f/m/d) to work in Modelling ore fabrics along comminution to predict liberation. 

Your tasks

Develop a methodlogy to predict breakage and liberation, including:

• Develoment and implementation of parametric, fast preferential breakage models, e.g. with stochastic tessellations
• Development and implementation of estimation methods for the model parameters, e.g. with machine learning or statistical methods
• Lab work and collection of samples and structured metadata along lab scale comminution experiments and validation of modelling results
• Evaluation of the forecasting capabilities of the methodology integrated within a flowsheet simulation with flotation
• Presentation of own results at international conferences, in peer-reviewed journal publications and in a PhD thesis
• Cosupervision of related MSc topics and cooperation with other associated PhD topics is highly encouraged

Your profile

• Completed university studies (Master/Diploma) in STEM fields with strong background on process modelling, applied mathematics, process engineering, geometallurgy or related field
• Experience in either stochastics, deep learning or minerals processing is needed
• Structured and solution-oriented working style, analytical thinking and above-average committment
• Excited about working in interdisciplinary teams in an international environment
• Very good English communication skills, written and oral
• Very good programming skills in at least one high level language (e.g. Julia, Python, R) are a requirement
