1.. IntroductionIn mineral processing, comminution accounts for a substantial portion of the energy consumed in the plant, almost 80%. Efforts to increase comminution efficiency come not only from the need for high production rates but also because of higher energy costs associated with the inherent low-efficiency of conventional comminution systems and the lower grade of ores that have to …
occluded ore: where the mineral can be released without very fi ne grinding; and dispersed ore: which forms the majority of deposits, and requires very fi ne grinding to liberate the mineral. Ore characterization Minerals can be classifi ed by their properties (optical, physical, electrical, magnetic) and by their chemical composition.

11.24 Metallic Minerals Processing 11.24.1 Process Description1-6 Metallic mineral processing typically involves the mining of ore from either open pit or underground mines; the crushing and grinding of ore; the separation of valuable minerals from matrix rock through various concentration steps; and at some operations, the drying, calcining ...
High Pressure Grinding Rolls have been used for the grinding of diamond and iron ores since about 1988. There are now about 40 machines operating world-wide in these industries. This number is still small in comparison to the > 450 machines employed in the cement and raw mate-rials industry.
Insufficient grinding may result in loss of valuable minerals in the tailings; over grinding wastes energy and may produce slimes that are difficult to treat. The nature of the boundaries between intergrown particles will show whether or not the rupturing of larger particles during grinding is likely to occur at grain boundaries.
pinion, gearbox, coupling, motor shaft and motor bearings, used within a conventional mill drive system. By mounting the rotor poles directly onto the mill, the mill itself becomes the rotor of the gearless motor.
