Particle Analysis in Mining and Minerals
In many cases, the valuable minerals are mixed with gangue, commercially useless material, and the ore must be separated. The first step of many separation processes is comminution (size reduction) followed by classification (separation by particle size) either for further grinding or the next step, concentration of the ore.

II. IMPORTANCE OF MINERALOGY IN MINERAL PROCESSING
From mineral processing point of view, it is important to identify the ore and gangue minerals (mineralogical study), their textural relationship (grain size, grain boundary relationship etc.). The mineralogical study also helps in the modal distribution of ore and gangue minerals which decides the grade of ore.

Ore Minerals : What are Ore Minerals?
Ore Minerals. An ore is a natural occurrence of rock or sediment which contains enough minerals with economically important elements, typically metals, that can be extracted from the deposit economically. The ores are extracted by mining for a profit from the earth; they are then refined (often by smelting) in order to extract the valuable

Minerals | Special Issue : Mineral Liberation
In mineral processing, liberation of valuable mineral from gangue minerals is the most important stage before the concentration process. Comminution, which leads to liberation, includes two types of random and non-random breakages. The contribution of random and non-random breakage is very important in modelling the liberation phenomenon.
