  • Mineral Beneficiation

    The objective of this project is to develop a novel and effective beneficiation process to upgrade critical minerals, increase utilisation of existing resources, and reduce costs and adverse impacts in processing of the ores.

  • Development of Advanced Coal Cleaning Technologies

    Separation of ultrafine coal particles from clay and water during a cleaning operation has been a long-term problem that the industry has faced. This project will develop advanced solid-solid and solid-liquid separation technologies, aiming to achieve high combustible recovery and low product moisture at low cost.
