A Study of the Relative Impact of Particle Size

the impact of changes in particle size distribution on gold recovery from a low-grade ore using sodium cyanide as a lixiviant. A gold oxide ore from a Ghanaian mining operation was used in this investigation. The ore was milled and prepared into feed sizes ranging from 50–90% passing 106 µm and leached over 24 hours using conventional bottle

Particle Analysis in Mining and Minerals HORIBA

Many of the particles encountered in mining are characterized by sieves (classifiers). Recent advances in computers, cameras, and software make image analysis practical for samples with sizes larger than several microns in diameter. As particle size decreases, sieving and/or dynamic image analysis becomes more arduous or impossible and laser diffraction becomes the technique of choice.

British Geological Survey CORE

The particle-size distributions quoted for gold do not reflect the particle-size distribution of the ore. For example 50% of the gold by weight may exist in a size fraction that only represents 10% of the ore by weight. Also the variation in the weight distribution of gold with particle-size depends upon the nature of the ore

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.
