than one face so that simple blasting patterns can be used to remove the rock. In the illustration that follows (Figure 8-4) shows a typical bench cut with two free faces and fired with one delay per row. Figure 8-5 indicates that the direction of throw of the blasted rock can be controlled by varying the delay pattern.

In a typical pyrytic gold ore, the gold is encapsulated within an iron sulfide crystal structure. Highly oxidized ores generally do not respond well to flotation. Advantages of the flotation process are that gold values are generally liberated at a fairly coarse particle size (28 mesh) which means that ore grinding costs are minimized.
