Purpose and goal
This project aim to test if synchrotron-based techniques can be used in the mining industry to improve the characterization of trace elements in ore samples. With an improved characterization, the metal recovery can potentially increase which would result in more sustainable mining. Another important goal for the project is to introduce the Swedish mining industry, through Boliden that is one of the leading metal producers in Europe, to the analytical capacity of a synchrotron facility.
Expected results and effects
Project partners Luleå University of Technology and Boliden Mineral will test how a conventional method for characterization of ore minerals and trace elements, automated mineralogy, compares to an advanced analysis by synchrotron-based micro-XRF. A positive effect from the project, if the tests prove useful from an industry perspective, is that the number of potential users of synchrotron facilities increase as another important basic industry is made aware of the capacity of a synchrotron.
Planned approach and implementation
Samples planned for use in this project have already been characterized by automated mineralogy in an ongoing CAMM2 PhD project. Suitable samples for synchrotron analysis will be selected, from discussions with beamline scientists at MAX IV or alternative international synchrotron. After micro-XRF analysis is performed at the synchrotron, data will be evaluated. Industry will take active part in all stages of the project, so that knowledge of synchrotron techniques will be transferred from expert users to industry.
