    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 Earth''s crust. In industry, it is an important unit operation in mineral processing, ceramics, electronics, and other fields, accomplished with

    Size Reduction and Energy Requirement - ScienceDirect
    So a measure of size or surface area before and after size reduction would indie the extent of energy expended in the comminution process. Hence if E was the energy used for a desired size reduction, which resulted in a change in surface area S, it has been found that , , , , :

    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.

    Energy and Environmental Profile of the U.S. Mining Industry 6 Lead and Zinc Lead and zinc ores are usually found together with gold and silver. A lead-zinc ore may also contain lead sulfide, zinc sulfide, iron sulfide, iron carbonate, and quartz. When zinc and lead sulfides are present in profitable amounts they are regarded as ore minerals.

    Energy Curves - CEEC (Coalition for Eco Efficient Comminution)
    The Size Specific Energy (SSE) intensity is a measure of how much energy is used in generating new sub 75 micron material. The SSE method has been used as an alternative to P80 reduction because it more accurately reflects that the majority of the energy is consumed in the generation of new surface area in the fines fraction (Ballantyne et al

    Particle Size Analysis for Mining and Minerals
    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 classifiion (separation by particle size) either for further grinding or the next step, concentration of the ore.

    Minerals | Free Full-Text | Testing of Ore Comminution
    Before concentration, metal ores have to be crushed and ground in order for the metal bearing minerals to be liberated. Sufficient size reduction by comminution is not only a prerequisite for any downstream physical separation, but is also the processing step within mineral processing that has the highest energy demand, and which, in practice, is often the limiting factor for plant capacity.
