If the particle distribution changes during the manufacturing process then the quality of the finished product will also change. Only a continuous monitoring of the particle size distribution can guarantee a constant product quality. Particle size determination methods There are different methods for determining the particle distribution.

A 100-mesh screen has 100 openings per inch, and so on. As the number indicating the mesh size increases, the size of the openings and thus the size of particles captured by the screen decreases. Higher mesh numbers = smaller particle sizes. It is very important to remember that mesh size is not a precise measurement of the mesh opening size.

As in (Schubert, 1987) a particle is defined as broken when 10% of its mass is lost. Thus a particle would count as broken if fragment mass m i is < 90% of initial particle mass m 0. Hereby m i is the fragment mass corresponding to initial particle size. In this study it is necessary to include the fragment mass below m i (m i-1). This is ...

Sulfur:gold particle size decreased, but the percent retained decreased. Creating a model of the ratios showed trends that can be used to predict ore-specific gold recovery. The best predictor is the mass:gold distribution, followed by the mass:sulfur distribution, which both describe gold liberation.
