The objective of mineral processing is to liberate and separate the valuable minerals from the gangue. In order to separate the valuable minerals from the gangue, it is necessary to crush and/or grind the rocks to a size where they are partially or fully exposed, or "liberated". The process of crushing and grinding is referred to as ...
DetailsThis process is called 'comminution' or 'size reduction'. Comminution may be carried out on either dry materials or slurries. Most mineral processing operations are conducted with water as the medium. This is called wet processing against dry processing. Crushing, grinding, milling, and vibration (feeding) are examples of comminution ...

Detailsunderground mines; the crushing and grinding of ore; the separation of valuable minerals from matrix rock through various concentration steps; and at some operations, the drying, calcining, or pelletizing of concentrates to ease further handling and refining. Figure 11.24-1 is a general flow diagram for metallic mineral processing.
DetailsMineral 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.
