  • - Test methods for characterizing ore comminution behavior

    Comminution test methods used within mineral processing have mainly been developed for selecting the most appropriate comminution technology for a given ore designing a grinding circuit as well as sizing the equipment needed. Existing test methods usually require comparatively large sample amounts and are time-consuming to conduct.

    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.
