On successful completion of the course students will be able to:
1. An appreciation of the place of coal and minerals processing in the Australian economy.
2. A Basic knowledge of geology and mining leading to the understanding of the concepts of ores and their processing needs.
3. Knowledge of how crushing and grinding of coal and ores liberates the valuable component.
4. An understanding of the scientific principles of size and density distribution of minerals and its application to size and density separation processes.
5. Understanding of the economic importance of the concentration of valuable minerals and how this is achieved.
6. An appreciation of the safety and environmental requirements of the mining industry.
7. An understanding of the design of coal / mineral processing plants.
