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.

Mineral liberation analysis gives the mass proportion of the target mineral occurring as liberated (degree of liberation) and also the association of the target mineral when not liberated. Analysis is performed for particle size fractions and this information is mostly used in defining the required grinding size for the concentration process.

liberation is -425 +300 µm. The knowledge of economic liberation of minerals have always been useful in mineral processing plants because it saves time and energy. Economic liberation can be determined by particle size distribution which have always been determined by sieve analysis of the mineral. In flotation, it has been confirmed that the
