Very few metallic mineral processing facilities will contain all of the operations depicted in this figure, but all facilities will use at least some of these operations in the process of separating valued minerals from the matrix rock. The number of crushing steps necessary to reduce ore to the proper size vary with the type of ore.

mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy. The primary operations are comminution and concentration, but there are other important operations

The primary process involved in the metallurgy of metals is pulverization, which involves the crushing of ores into fine powder in a crusher. The Concentration of Ores: The ores extracted from the earth''s crust contains a large number of unwanted impurities called gangue mixed with them, such as quartz, silicates, sand, feldspar, mica, etc.

Most rock deposits contain metals or minerals, but when the concentration of valuable minerals or metals is too low to justify mining, it is considered a waste or gangue material. Within an ore body, valuable minerals are surrounded by gangue and it is the primary function of mineral processing , to liberate and concentrate those valuable minerals.

Crushing is the first mechanical stage in the process of comminution in which the main objective is the liberation of the valuable minerals from the gangue. Primary crushers are commonly designed to operate 75% of the available time, mainly because of interruptions caused by insufficient crusher feed and by mechanical delays in the crusher.
