Mineral processing | metallurgy | Britannica

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 ...

Screening is a key operation in a crushing plant that ensures adequate product quality of aggregates in mineral processing. The screening process can be divided into the two sub-processes of stratification and passage. The stratification process is affected by the relative difference between various properties, such as particle shape, size distribution, and material density.

1. Introduction. Jigging is a gravity separation method commonly used by the mineral industry to separate coal, diamonds and other minerals on the basis of particle size and/or density (Gupta, 2003).Jigging units characteristically dilate the particle bed by an upward blast of water and particles of different densities settle at different velocities.
