Particle Size Analysis for Mining and Minerals ...

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.
