The Coalition for Energy Efficient Comminution (CEEC) has been established and is supported by a broad range of mining sector companies keen to accelerate awareness, knowledge transfer and, by implication, improve energy and cost outcomes in the substantive area of comminution.
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.
populate energy curves for gold, copper, platinum, nickel commodities; adopt metrics and methodologies for benchmarking of industrial comminution efficiency within the hard rock mining sector developed by the GMSG Industrial Comminution Standards Working Group. CEEC will host the energy curve program for all operators to use in full confidence.

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 Earth's crust. In industry, it is an important unit operation in mineral processing, ceramics, electronics, and other fields, accomplished with ...
Anglo Platinum's Chris Rule and colleagues stated that the Polysius Polycom HPGR has come of age, offering appropriate roll wear-abatement technology and proving itself as an alternative comminution device for hard-rock applications. The Polycom can be specified as to roll diameter, roll width, roll speed, hydraulic pressure and bearing size.
As mentioned above, the HPGR process and product properties are very different from conventional comminution equipment. It provides a new option in hard-rock mining's toolbox, which is badly needed to meet the specific challenges of today's mineral-processing industry.

In many cases, the valuable minerals are mixed with gangue, commercially useless material, and the ore must be separated. The first step of many separation processes is comminution (size reduction) followed by classification (separation by particle size) either for further grinding or the next step, concentration of the ore.
