A review of state

Since the size of run-of-mine coal can vary widely, the size reduction and size separation processes utilized in coal preparation provide a convenient mechanism to regulate the product size. Second, the removal of ash and other incombustible materials leads to less waste production during the electric generation process.

Proximate and Ultimate Analysis | Mining | SGS

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.
