    Mineral processing can involve four general types of unit operation: comminution particle size reduction; sizing separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering solid/liquid separation. In all of these processes, the most important considerations are the economics of the processes and this is dictated by the grade and recovery of the final product.

    Mineral processing can involve four general types of unit operation: comminution particle size reduction; sizing separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering solid/liquid separation. In all of these processes, the most important considerations are the economics of the processes and this is dictated by the grade and recovery of the final product. To do this, the mineralogy of the ore needs to be considered as this dictates the amount of liberation required and the processes that can occur. The smaller the particles processes, the greater the theoretical grade and recovery of the final product, but this however is difficult to do with fine particles as they prevent certain concentration processes from occurring. Comminution is 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. Crushing is normally carried out on "run-of-mine" ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material. In comminution, the size reduction of particles is done by three types of forces: compression, impact and attrition. Compression and impact forces are extensively used in crushing operations while attrition is the dominant force in grinding. The primarily used equipment in crushing are jaw crushers, gyratory crushers and cone crushers whereas rod mills and ball mills, usually closed circuited with a classifier unit, are generally employed for grinding purposes in a mineral processing plant. Crushing is a dry process whereas grinding is generally performed wet and hence is more energy intensive. Sizing is 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 numb

    IntroductionLocation of The Crusher in An Underground MineMaterial HandlingTechnology and Equipment SelectionCostingDust ControlConclusions and RecommendationsReferencesCrushers play an important role in the material handling process for underground mine operations. The main purpose of a crusher is the size reduction of the feed. This size reduction is achieved by applying a force to the material, creating cracks in the material which in the end will cause the material to break into smaller pieces. There are two categories of crushers based on the way the force is applied to the material. For crushers of the first category apply force via pressure, the crushers of the second categor

    Crushing is an important step in the complex process of mineral processing (Fig. 1). In open pit mines, rock chunks with edge lengths of 2 m have to be processed.
