The classic pre-crushing plant serves to relieve the primary crusher by using a HAVER NIAGARA eccentric screening machine. If needed an additional screen deck allows the screening off of stony earth. If the screening material is unsuitable for further processing, it can then be directly screened away.
Dedicated primary and secondary crushing circuits, tertiary crushing using a high-pressure grinding rolls (HPGR) unit, material handling and stacking conveyors, and a carbon-in-column (CIC) adsorption plant would be installed.

Primary crushing brings run-of-mine ore down to a maximum size of the order 4″ to 6″ in average diameter; secondary crushing receives feed at −6″ and reduces it to below "Dry" crushing includes work on ore as mined, which may be somewhat moist when delivered. It is succeeded by comminution in water, arbitrarily called "grinding".
Crushing to the proper size usually occurs in stages because rapid size reduction, accomplished by applying large forces, commonly results in the production of excessive fines (Rollings and Rollings 1996). After primary crushing, the material is run through one or more secondary crushers.
