Flotation kinetics of a pyritic gold ore The gold was mostly associated with pyrite in native form as inclusions and was also in contact with pyrite along the boundaries of nonsulphide gangue. Gold recoveries were found to increase from % to % as the particles size decreased from an F 80 of 205 μm to 53 μm.

In many cases, the valuable minerals are mixed with gangue, commercially useless material, and the ore must be separated. The first step of many separation processes is comminution (size reduction) followed by classification (separation by particle size) either for further grinding or the next step, concentration of the ore.
