(COF) and the coarser and denser particles reporting to the cyclone underflow (CUF) for further grinding. Eventually, the ore is ground fine enough (typically in the range of 75-250 µm P 80) and reports to the cyclone overflow. From there, the fine gold particles that have reported to the cyclone overflow, are

Laplante and Marois, 1991). The retention of GRG within the grinding circuit allows for effective gravity recovery of gold from within the grinding circuit. A typical partition curve for both the ore and GRG, presented in Figure 3, illustrates the significant difference in the partition behaviour of the gold relative to the ore.
