Figure 5. Grinding Time vs. 80% Passing Since the ultimate goal of the experiment is to determine the mesh-of-grind which is the time it will take for the grinding process to completely liberate the ore in its proper size, the 80% passing size of each trial is plotted against the grinding time and with the use of the average 80% passing, the mesh-of-grind is determined and is …

The term 'Mesh' is used to describe the size of an abrasive particle. In some instances, such as with Aluminum Oxide Grit or Silicon Carbide Grit, a single number is used.This does not mean every particle in that product is exactly that size but rather than mesh size indicator is approximately the mean or average size of the range of particles in that grade.

Overall gold recovery was unaffected by primary grind size over the range of 73 to 197µm P80. Gold from the feed was 95 to 97 percent recovered into the pan and rougher concentrates, containing between 20 to 33 percent of the feed mass. Higher mass recoveries were observed at the finer primary grind sizes.
