Mineral Processing

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 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 ...

Crushing and Screening for Mineral Processing Success

While it''s difficult to control the composition or mineral makeup of the feed to the ore sorter, you can have significant influence on one major performance factor: particle size. From a process point of view, it''s necessary to make sure the rocks being fed are sufficiently heterogeneous to enable separation.

Spiral Concentrators

Spiral concentrators are a gravity based concentrating device, that separates light density granular and sandy (18 mesh to 200 mesh (1 mm to 0.075 microns)) consistency material from heavier density material. In order to have a good separation, there should be a difference in SG''s of at least 1.0.
