25.3 Crushing and milling Mining of mineral resources ...
This process of reducing the size of the rocks requires a lot of energy. Just image how hard it is to break a rock. How much more energy do you think is needed to crush a rock until it is like sand? This is one of the steps in the mining process that is very expensive because energy is needed to drive the process.

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.
