Particle Size. The particle size to which the ore is ground depends on the nature of the ore. The grind must be fine enough to liberate the mineral grain from associated rock, but producing too small a particle size is both expensive and detrimental to recovery. Froth flotation is generally limited to size fractions between roughly 65 and 100 mesh.

Fig. 3. The sand particle size distribution was considerably narrower than that of the chrysocolla: whereas 35% by volume of the chrysocolla particles were under 20 µm in diameter only 18% by volume of the sand was in this particle size range. The volume passing 100 µm was 77% for the sand and 83% for the chrysocolla.

4) Particle Size Distribution. The thinking is that the size distribution of the target metal will be coarser in cyclone underflow as opposed to cyclone feed and the fine particles in cyclone feed can't be recovered gravimetrically anyway. In light of development of enhanced gravity concentration devices, the foregoing maxims should be revisited.

· Murphy agrees: "If you plotted flotation recovery against particle size, recovery is relatively high for particles in the 50-150μm range. Outside this range, the recovery falls off rapidly. At the coarse end, it quickly reaches a point in most systems where the particles are not recovered. In producing plants, it is around the 200μm mark. Getting particles at this coarse …

The particle-size distribution (PSD) of a powder, or granular material, or particles dispersed in fluid, is a list of values or a mathematical function that defines the relative amount, typically by mass, of particles present according to size. Significant energy is usually required to disintegrate soil, etc. particles into the PSD that is then called a grain size distribution.
