Fragmentation and its Impact on Downstream Processing

The perennial challenge facing mining and minerals operators is to improve productivity, usually by a combination of cost reduction and performance improvement. In a typical production situation involving mining and processing activities, the standard approach has long been to seek improvements in each activity, effectively in isolation from each other. However, the realisation is growing that there is considerable potential to achieve really substantial productivity gains by much improved integration of mining and processing with the key being to consider what is best in the total sense. Some of the linkages between fragmentation in mining and downstream processing are considered in this paper. These linkages involve technical, operational and economic Considerations.
