A short history of mineral processing Fathi Habashi Laval University, Quebec City, Canada ABSTRACT: Crushing and grinding of ores and their beneficiation by washing away gangue minerals has been practiced since ancient times. Primitive crushing was done by hand pounding the ore with a hard stone then by using metallic hammers.
Mineral processing, also known as ore dressing, is the process of separating commercially valuable minerals from their ores. Mineral processing involves four general types of unit operation: Comminution – particle size reduction ( crushing, grinding, etc.) Sizing – separation of particle sizes ( screening, classifiion etc.)

A. Gupta, Yan, in Mineral Processing Design and Operation, 2006 Roll Crusher Circuit Design. Roll crushers are generally not used as primary crushers for hard ores. Even for softer ores, like chalcocite and chalcopyrite they have been used as secondary crushers. Choke feeding is not advisable as it tends to produce particles of irregular size.

22/03/2013 · Crushing and Grinding. Crushing is the first mechanical stage in the process of comminution in which the main objective is the liberation of the valuable minerals from the gangue. In the nature minerals are usually intergrowth with other mineral species. In order to separate them, they must be unlocked through comminution (crushing and grinding).
