Comminution is the process in which the rock/ore is reduced to desired size where liberation of the minerals are maximum without changing the chemical and physical properties of the rock. From: Essentials of Mineral Exploration and Evaluation, 2016. Related terms: Gangue; Crusher; Litter
MTG understands, Comminution is one of the largest energy consumer in a mine with a major implication in cost and carbon footprint. We bring about a number of integrated strategies which can improve efficiencies and reduce energy use.
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 timeconsuming to conduct.

Comminution is the oldest process technology and it is also one of the largest, most extensive and most complex. It is very large because of the huge amounts of rocks and particles which are broken annually to support the world's population, it is extensive because of the wide range of processes for which comminution must be used, and it is complex because of the many variables which affect its .
Comminution is one of the most demanding mineral technology processes because selection of the correct crushing and grinding process guarantees a successful separation process.
