Mineral processing - Wikipedia
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 stone properties; and dewatering – solid/liquid separation. In all of these processes, the most ...
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.

P roportion of Energy Attributable to Comminution
energy usage data and the lack of a common basis for reporting the fraction of energy in mining that is attributable to comminution. This study should form a reliable basis from which to assess both demand and opportunities to reduce energy consumption. The proportion of milling energy was calculated for the major producers in the Australian gold
Size Reduction by Grinding as an Important Stage in Recycling
Size Reduction by Grinding as an Important Stage in Recycling 275 for example, multi-edge grinders characterized by low energy consumption, low noise level and good repeatability of stone classes [4, 13]. Cutting between two cutting edges is widely used in cutting mills, in particular for grinding of plastics and cross-linked elastomers [48, 3].

2.12. Latest developments in microwave processing of minerals ores. The mechanical size reduction of solids is an energy intensive and highly inefficient process. Therefore, there is great incentive to improve the efficiency of size reduction and mineral separation processes.
Comminution - Wikipedia
Comminution is the reduction of solid materials from one average particle size to a smaller average particle size, by crushing, grinding, cutting, vibrating, or other processes. In geology, it occurs naturally during faulting in the upper part of the Earths crust. In industry, it is an important unit operation in mineral processing, ceramics, electronics, and other fields, accomplished with ...
