Mineral Recovery - an overview ScienceDirect Topics

Heating and quenching rock can enhance liberation and increase mineral recovery in mineral processing. If the objective of size reduction is to liberate the valuable mineral component of an ore, then ideally fracture should follow intergranular paths, that is, grain boundaries. If so, the result would be liberation with minimum size reduction.
