Separates the different sized ore from mine into two or more streams, each containg a different size range of particles. In industial, two types of screens […]
Most metals are present in extremely small concentrations in nature, and none of this metals can be recovered economically at these concentrations.
Because most minerals are finely disseminated and intimately associated with the gangue, they must be initially “unlocked” or “liberated” before separation can be undertaken. This is achieved by comminution, in which the particle size of the ore is progressively reduced until the clean particles of mineral can be separated by such methods as are available. Comminution in the mineral processing plant, or “mill,” takes place as a sequence of crushing and grinding processes.

Grinding is the last stage in the comminution process where particles are reduced in size by a combination of impact and abrasion, either dry, or more […]
