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.
Open or Closed Circuit Crushing
“Stage-crushing,” as we use the term here, applies to open-circuit reduction in a flow line comprising two or more crushing stages, with scalping between each stage, but without close-circuiting any stage upon itself; except, perhaps, the final one.

Mineral processing | metallurgy | Britannica
In order to produce a crushed material suitable for use as mill feed (100 percent of the pieces must be less than 10 to 14 millimetres, or 0.4 to 0.6 inch, in diameter), crushing is done in stages. In the primary stage, the devices used are mostly jaw crushers with openings as wide as two metres.
Crushing & Grinding – The Anchor House, Inc.
Sep 09, 2016 · Each possible mineral recovery process has a certain size range of best performance, and the final product of the crushing/grinding circuit must match the chosen process size requirements. Proper grinding is critical in order to get good metallurgical test results, as the entirety of downstream processing is dependent on optimal grinding and recovery at this stage.
