During ore dressing, the crude ore is reduced in size to a point where each mineral grain becomes essentially free so as to make separation between them. Such a phenomenon of making the mineral grains free from gangue in an ore is termed as liberation. This is practically carried out by size reduction performed by crushers and grinding mills.
