# comminution in ore beneficiation

### VALUE ADDITION TO ORES THROUGH BENEFICIATION

(through grinding). The statistical count of interlocked grains, 'ore minerals free of gangue' (liberated ore) and 'gangue minerals free of ore minerals' (liberarated gangue) gives the quantitative percentage of liberation [1]. This data is useful in deciding the extent of liberation required for a desired economy of comminution and beneficiation.

### Comminution - Wikipedia

Comminution is the reduction of solid materials from one average particle size to a smaller average particle size, by crushing, grinding, cutting, vibrating, or other processes. In geology, it occurs naturally during faulting in the upper part of the Earth's crust. In industry, it is an important unit operation in mineral processing, ceramics, electronics, and other fields, accomplished with
