    Global ore grades are declining. In addition, orebodies are getting increasingly complex, with the valuable minerals often more finely disseminated and therefore more difficult to liberate from the associated gangue. As mining companies deal with more complex, refractory and lower grade orebodies, the need for fine and ultra fine grinding

    A "refractory" gold ore is an ore that has ultra fine gold particles disseminated throughout its gold occluded minerals. These ores are naturally resistant to recovery by standard cyanidation and carbon adsorption processes. These refractory ores require pre treatment in order for cyanidation to be effective in recovery of the gold. A
