A "fine" grind in a gold production plant might produce a particle size distribution in which 80% of the ore is finer than 44 µm. Ultra-fine grinding can be defined as a process that produces an 80% passing size of 20 µm or less. Depending on the size distribution of gold particles, ultra-fine grinding can be sufficient to improve leach ...
