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

Particle Size Conversion Table | Sigma-Aldrich

For example, if the particle size of a material is described as -4 +40 mesh, then 90% or more of the material will pass through a 4-mesh sieve (particles smaller than 4.76 mm) and be retained by a 40-mesh sieve (particles larger than 0.420 mm). If a material is described as -40 mesh, then 90% or more of the material will pass through a 40-mesh sieve (particles smaller than 0.420 mm).
