Simply, the process of screening ore material is such that the material is passed through a screen - or sometimes multiple screens - to classify the particles according to their respective sizes and shapes. Another use for screening is to determine the percentage of fines present in the ore and, as common practice, in the oversize.

The principles behind modern particle sorting remain the same. Essentially, your aim should be to collect the valuable particles and discard the barren, or low-grade ones, in order to generate more metal per tonne. When processed, this can improve mine economics and reduce environmental impacts like energy consumption and tailings footprint.

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.
