Click to chat· Flotation as a process is defined as the separation of "finely divided particles from each other by means of using air bubbles under hydrodynamic environment" (6). Froth flotation entails crushing and grinding of the ore to obtain a proper liberation of particles to apply flotation principles. The process is conducted in water from the
Click to chat· The attraction of semi-autogenous grinding in copper operations is that they can accommodate ores that are hard or soft wet or dry sticky or otherwise. The SAG mill can handle everything that is presented to it regardless of coarseness or fineness or hardness or moisture content and from it prepare satisfactory feed for subsequent secondary grinding by conventional means to the required flotation
