16. Test Methods for Characterising Ore Comminution Behavior in Geometallurgy
Abstract : Comminution test methods used within mineral processing have mainly been developed for selecting the most appropriate comminution technology for a given ore, designing a grinding circuit as well as sizing the equipment needed. Existing test methods usually require comparatively large sample amounts and are time-consuming to conduct. READ MORE

17. Development of the mineralogical path for geometallurgical modeling of iron ores
Abstract : The demands for more effective utilization of ore bodies and proper risk management in the mining industry have resulted in a new cross discipline called geometallurgy. Geometallurgy connects geological, mineral processing and subsequent downstream processing information together to provide a comprehensive model to be used in production planning and management.

18. Effects of loading mechanisms and texture on ore breakage – A multidimensional study
Abstract : In comminution machines, the product properties (particle size distribution, mineral liberation characteristics) and process consumables (energy for size reduction, wear) are affected by various parameters. On the one hand, understanding and optimizing these parameters can provide an energy efficient process and a specified product. READ MORE

19. Efficient mineral liberation – Multidimensional investigation of mechanical stress and ore texture
Abstract : Within mineral comminution, the product properties (such as particle size distribution and mineral liberation characteristics) along with process efficiency are affected by material related and process environment factors. Understanding and optimizing these factors leads to designing and developing an energy-efficient process with a specified product. READ MORE

20. Wet Low-Intensity Magnetic Separation: Measurement methods and Modelling
Abstract : In the mining industry, ferromagnetic particles (e.g. magnetite) are concentrated using wet low-intensity magnetic separation (LIMS). Mineral particles in suspension with water are pumped into the separator tank, and a magnetic concentrate is extracted by use of magnetic forces. READ MORE
