    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, 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

Ore Dressing Methods

Gold Ore ProcessingMethods of Ore TreatmentAmalgamationConcentrationCyanidationGold-Milling DataThe fact that a product of high value and small bulk can be produced at a gold mine, often by relatively simple milling processes, has made it possible to operate gold mines successfully in remote and inhospitable regions where high costs of transportation, fuel, and power would make it impossible to exploit profitably base-metal ores of equal dollar value. As a result, in many instances gold-mine development has been the advance guard of civilization in regions where other mineral resources...

Ball mill Wikipedia

The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of ferrous and non-ferrous metals. The ball mill can grind ores and other materials either wet or dry.

Crushing in Mineral Processing

In mineral processing or metallurgy, the first stage of comminution is crushing. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface. Less abrasive and softer rocks or stones
