A simple definition of a "screen" is a machine with surface(s) used to classify materials by size. Screening is defined as "The mechanical process which accomplishes a division of particles on the basis of size and their acceptance or rejection by a screening surface". Knowledge of screening comes mainly from ex…

Screening is the passing of material through definite and uniform apertures is the only true and accurate means of grading to a required particle size. Air separation and hydraulic classification depend upon gravity and particle shape, and result in the segregation and retention of material of higher specific gravity and lower surface area irrespective of size.

The number of crushing steps necessary to reduce ore to the proper size vary with the type of ore. Hard ores, including some copper, gold, iron, and molybdenum ores, may require as much as a tertiary crushing. Softer ores, such as some uranium, bauxite, and titanium/zirconium ores, require little or no crushing.
