CHAPTER 1 MINERAL DRESSING

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.

Mineral Processing - an overview | ScienceDirect Topics

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.
