Particle Size Analysis for Mining and Minerals Applications - HORIBA

Particle size plays an important role in mining and mineral separation. . The first step of many separation processes is comminution (size reduction) followed by classification (separation by particle size) either for further grinding or the . Many of the particles encountered in mining are characterized by sieves (classifiers).

Properties of Minerals for Processing

other malleable minerals are crushed, the metallics are left on the sieve as flat scales or spherical particles. When such ores are sampled, in order to extract metallics, care should be taken. In such cases, initially the original sample must be carefully weighed followed by a separate preservation of particles found on.

Do I need to grind soil for particle size analysis, using sieves?

Routinely we air dry soil samples collected from the field, remove dirt, grasses etc, put it in wooden mortar and grind mildly with wooden pestle to avoid crushing minerals so that they don't get mixed up in soil matrix and also to avoid mixing up other minerals viz Fe etc. This is followed by sieving for getting 2 mm size soil.

Purdue University :: Crushing and Sieving

When a sample arrives it is first crushed and sieved. This is to obtain the correct grain size for the rest of the separation process. The ideal grain size is 0.25-0.50mm. There are two crushing machines available; a jaw-crusher and a disc-pulverizer. Samples are usually run through the jaw-crusher first, and then the pulverizer.

the packing of very small particles around them. One of these large grains in a small sample taken for analyses (e.g. ICP emission spectrography or neutron activation analyses) could produce anomalous results, particularly if the large grain is monomineralic. Sieving during crushing should remove this problem.
