separation or pelletizing and will vary with the ore characteristics (McNab et.al., 2009). Due to the high applied pressure in the HPGR grinding process and depending on the ore characteristics it is possible to create agglomerates (flakes) in the HPGR product. One example for a gold ore is given in Figure 1.
