back to the mill and being overground. Excess grinding of these particles can result in slimes that are difficult to recover in downstream flotation circuits. Recovering these particles from the circulating load can boost overall plant recovery, improve mill capacity, and also lead to improved concentrate dewatering characteristics.

The process aims to float coarse, high-grade particles early in the process flowsheet. Typically, a portion of the cyclone underflow stream from the ball mill circuit (i.e., the circulating load) comprises the feed to the flash flotation cell, with the flotation tails returning to the grinding mill (Figure 12.87).
