PhD position in modelling of sustainable milling technology

Updated: about 3 hours ago
Deadline: 31 Jul 2024

How can we reduce energy consumption in the mining industry? The entire mining industry consumes approximately 3.5% of the total global energy. About a quarter of this is used for comminution which is the process of reducing the size of mined ore into particles small enough to separate and retrieve the valuable minerals.

This PhD position aims to accelerate the adoption of a novel low energy crushing and milling (comminution) technology for mining and mineral processing. The PhD research is focused on modelling and simulation, laboratory experiments and analysis of the critical mechanical interaction between the machine and the rock particles, which is where the energy use is happening. The PhD student will be part of a research group Chalmers Rock Processing Systems which has a wide international collaboration when it comes to aggregates production and minerals processing.

Project description
The PhD research position is within the Vinnova-Embrapii project - “Modelling, simulating and benchmarking a new energy-efficient and sustainable comminution technology”. The scope of the project is to accurately model the single particle fracture mechanism of the low energy milling machine, enabling it to be simulated and designed at the production scale together with other project stakeholders like Federal University of Rio de Janeiro, Centre for Mineral Technology, Vale S.A. and Comminution Reimagined Sweden AB. The project objectives include detailed understanding and accurate modelling of the single particle fracture mechanism and particle size reduction from an engineering perspective to achieve mineral liberation and recovery. This will include data collection, laboratory experiments and analysis of the mechanical interaction of the crushing/milling machine with the rock particles through modelling and simulation. You will work closely with other PhD students and senior scientists within the Chalmers Rock Processing Systems group as well as other researchers within the Vinnova-Embrapii project and other international collaborations.

Department of Industrial and Materials Science
The main competencies at the Department of Industrial and Materials Science are found in the areas of: Human-Technology Interaction, Form and Function, Modeling and Simulation, Product Development, Material, Production and in the interaction between these areas. The research develops the industrial process from need to finished product, while creating added value. By combining skills throughout the chain, the department is distinguished both nationally and internationally. Here we gather internationally competitive researchers, in dynamic and outstanding research environments, as well as in national and international research networks.

Information about the division
The position will be based at the Division of Product Development . The division provides new methods and tools for virtual platform-based development of sustainable and robust products, as well as product development processes in a lifecycle perspective. The research is based on design methodology, mechanical engineering, mechanics, statistics, information technology and optimization.
The Machine Element Group (also called Chalmers Rock Processing Systems group) deals with the modelling and optimization of components, machines and systems in industrial applications. Current research activities are centered around equipment and process modelling, optimization and environmental impact assessments for aggregate production and minerals processing in mining for metal extraction.

Major responsibilities
As a PhD student, your main responsibility is to pursue your own doctoral studies, which comprises work on the modelling new technology for crushing/milling within the Vinnova-Embrapii project - “Modelling, simulating and benchmarking a new energy-efficient and sustainable comminution technology”. You are expected to work independently, have the ability to plan and organize your work, work in close collaboration with other group members and partners, and be able to communicate scientific results, both orally and in written form in English.

The doctoral program is supposed to lead to the doctoral degree, equivalent to four years of full-time studies, which includes research, coursework, and participation in seminars and conferences.
The position also includes teaching at Chalmers' undergraduate level corresponding to 20 percent of your working hours. You are expected to write a licentiate thesis within 2.5 years and defend your doctoral thesis within 5 years.
