The plant and infrastructure facilities have been located as close to the open pit mine as possible on the limestone bluff to the west of the site. The escarpment will be cut back to a general elevation of 254 m.a.s.l. to ensure clearance above the water table for the plant facilities. The
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.
