This process of size reduction is called comminution.

By connecting mineral liberation information with a comminution model the optimal conditions can be examined a priori. However, this remains a challenge since mineral composition and texture information (e.g. the mineral grain sizes) have not been efficiently used to predict the liberation of mineral particles

WebIn mineral processing the relationship between the mineral (micro) textures and liberation has been a separate research subject for a long time. Basically the aim has been to forecast the liberation distribution from a two-dimensional picture of an ore. This is generally called the liberation model.
