Mineral processing, mineral beneficiation, or upgradation involves handling three primary types of ROM material, which have been blasted, fragmented, and brought out from an in situ position. These materials can be used directly or by simple or complex processing and even by applying extractive metallurgy like hydrometallurgical or pyrometallurgical methods.

Liberation . In process mineralogy, the degree of liberation of a mineral is generally calculated from examining 2D sections of a statistically representative set of particles containing the mineral of interest. The degree of liberation is typically based on the area% of the mineral grain(s) of interest in a particle (figure below).

Minerals Special Issue : Mineral Liberation

Jun 30, 2020 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.
