Particle-size distribution Wikipedia

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.

Effect of particles size range on iron ore flotation

The differences in particle size distributions and the specific surface area may explain the different flotation behavior of the distinct size fractions. The split flotation circuits for coarse and fine particles indicated an increase of 3% points in the metallurgical recovery with reduction of SiO2 content in final concentrate, increase of etheramine dosage and reduction of corn starch dosage.

Barry Wills' blog: Flotation Chemistry vs Flotation Physics

Coarse particle flotation is not about concentrate grade, it is about tailings grade. If 50% of the mass can be rejected at 1 mm with only a couple of percent loss of metal then excellent This depends on liberation and the size distribution of feed to flotation.If one is lucky with his ore characteristics,

Ore Dressing Analysers for Particle Size and Shape

The particle size is of particular importance in this process. If the particles are too large, unwanted accessory minerals cannot be separated from the ore. The ore concentrate obtained only has a low purity. Overgrinding, on the other hand, results in high milling costs and low throughput as well as an increased need for chemicals in flotation.

Conditioners also serve a useful function in that swings in ore grade, particle size distribution, or other flotation variable tend to be partially homogenized and dampened during the conditioning unit operation. For example, in small installations it is not unusual to experience wide swings in feed grade.
