1. 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

2. 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

3. Development of a geometallurgical framework for iron ores - A mineralogical approach to particle-based modeling
Abstract : The demands for efficient utilization of ore bodies and proper risk management in the mining industry have resulted in a new cross-disciplinary subject 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.

4. Geometallurgy of a complex ore : Lappberget Zn-Pb-Ag-(Cu-Au) deposit, Garpenberg mine, Sweden
Abstract : Complex ores, in this instance, a polymetallic base metal ore with additional precious and penalty elements, pose particularly tough challenges for successful production forecasts. Plant performance and recoveries for complex ores are more difficult to predict due to the larger number of variables that must be considered, tracked, and characterized during the multi-stage separation process.

5. Particle generation for geometallurgical process modeling
Abstract : A geometallurgical model is the combination of a spatial model representing an ore deposit and a process model representing the comminution and concentration steps in beneficiation. The process model itself usually consists of several unit models. READ MORE
