  • 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 ...

  • 11.24 Metallic Minerals Processing

    At most metallic mineral processing plants, each process operation requires several types of equipment. A single crushing operation likely includes a hopper or ore dump, screen(s), crusher, surge bin, apron feeder, and conveyor belt transfer points. Emissions from these various pieces of equipment are often ducted to a single control device.

  • How Ore Sorting Leads to Mineral Processing Success

    Impact crushers are known for high reduction ratios and producing cubed-shaped rock particles. However, they typically generate the largest amounts of fines and are ill-suited for ore sorting. Jaw crushers are usually used in tandem with cone crushers. The jaw crusher is the primary crusher in a comminution circuit for ore sorting and mineral ...
