Control devices also influence particle size distributions because each device has a different control efficiency for different particle size ranges. For example, a cyclone has a collection efficiency of about 30 percent for 1.0-pm particles and about 93 to 98 percent for particles in the 20- to 44-ym size range.

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.

weight distribution of gold with particle-size depends upon the nature of the ore ( and for alluvial gold the source area). Some alluvial gold deposits may contain a significant amount of fine grained gold whereas others will contain virtually none. 2.1. Alluvial Gold Generally the particle-size of alluvial gold falls into the range 5 mm to 100 pm.

Gold Extraction and Recovery Processes - Semantic Scholar

In a typical pyrytic gold ore, the gold is encapsulated within an iron sulfide crystal structure. Highly oxidized ores generally do not respond well to flotation. Advantages of the flotation process are that gold values are generally liberated at a fairly coarse particle size (28 mesh) which means that ore grinding costs are minimized.
