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 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.

Particle Characterization in Mining

Sep 06, 2019· There are many sub-methods in this category, such as jigs, sluices, spirals, shaking tables, fine particle separators, and hydrosizers and cyclones, which enable a rough estimate of the size of the particles (and the distribution of particle sizes) to be determined by the heavier particles falling/sinking further than lighter, i.e. smaller

Lecture 2: An introduction to mining

The ore is dumped in a crusher which crushes the rocks with mechanical force to smaller pieces, usually the size of gravel. The material is then taken to a mill to further reduce the particle size of the material, producing a fine sand or powder. There are different types of milling.
