— In mineral processing, the reduction of minerals by crushing and grinding may be regarded as having one or other of two main objectives: the attainment of a size appropriate for the direct industrial application of the mineral, e.g. barytes, sand, aggregate; or the release of metallic or ore inclusions from an unwanted matrix with a view to …

— Before separation, the run-of-mine ore needs to be crushed and ground down to a specific particle size to liberate the minerals as much as possible. However, crushing and grinding consumes a lot of energy. As the particle size becomes finer and finer, the grinding energy consumption increases exponentially.
