Beneficiation production line also can be divided depending on the materials, for example: graphite ore dressing production line, magnesium metal separation production line, or ash beneficiation production line and so on. Theses are the process of separating commercially valuable minerals from their ores. It can involve four general types of unit operation: comminution, sizing, concentration and dewatering.

Comminution refers to particle size reduction of materials. Comminution may be carried out on either dry materials or slurries. Crushing and grinding are the two primary comminution processes.
Sizing refers to the general term for separation of particles according to their size. The simplest sizing process is screening, or passing the particles to be sized through a screen or number of screens.
Concentration refers to taking advantage of physical and surface chemical properties. In any particular case, the method chosen will depend on the relative physical and surface chemical properties of the mineral and the gangue.
Dewatering refers to remove water contained in particles, it is an important process in mineral processing. The purpose of dewatering is to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue.
