Comminution | Centre for Minerals Research

Comminution: Comminution utilises energy to reduce the size of ore particles in order to liberate embedded mineral grains so that they can be recovered in the subsequent process stages. The research under this theme focusses on understanding how energy is used in devices that use different breakage mechanisms to achieve size reduction and how energy is utilised in different comminution …

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.

In mineral processing, all ores will have an optimum particle size which maximizes the economic benefits from the net smelter return while minimizing the cost of crushing and grinding. If the particle size is too coarse there will be inadequate liberation, limiting recovery (and thus revenue) in the separation stage. If the grind is too fine, the grinding costs will exceed any increment in ...
