Optimizing mining operations

For example, in a hard rock mining situa-tion (eg, copper or gold), mining engi-neers often control costs by reducing blasting 2. This ends up increasing overall cost of the operations because poorly fragmented material is delivered to the plant, dramatically increasing milling costs and, more importantly, decreasing throughput.
