In the past, ore fragmentation, comminution, processing, and concentration were viewed as isolated activities, each optimised separately. Today, the approach has evolved significantly, with every process integrated into the overall recovery effort. This course introduces key concepts of the mineral extraction value chain, placing a strong emphasis on the initial comminution stage (i.e. drilling and blasting) and its influence on subsequent downstream activities. Additionally, the course will introduce practical tools and processes used to implement integrated optimisation strategies, such as “mine to mill' and value-based ore control.
In the past mineral extraction, comminution and mineral concentration processes were seen as unitary activities and were generally optimised in isolation. Nowadays the approach to continuous improvement has changed, with every process becoming an integral part of the overall recovery effort. At the centre of the optimisation process is drilling and blasting which is considered to be the most important stage of the comminution process because of its impact on overall mining and processing costs and in particular crushing and grinding performance. This course provides the foundation for understanding the key stages of the value chain focussing on skills to optimise mining extraction processes by the implementation of leadingᅠpractices in blast design, analysis and continuous improvement. The course will include the following aspects:
Some prior knowledge in open pit and underground mining methods and systems is recommended, as well as a basic understanding of conventional ore handling and downstream processing stages.
We recommend completing the following courses before enrolling in this one:
