Smelting is ...
In broader terms, mineral processing consists of two functions. Firstly, it involves the preparation and liberation, of the valuable minerals from waste minerals and secondly, the separation these values into two or more products, called concentrates. The term separation in this case is synonymous with concentration.

Gravity Concentration — the separation of minerals by virtue of specific gravity — is one of the oldest forms of mineral processing. Whilst its relative importance has declined in the twentieth century, the high cost of alternative processes, along with the development of a range of high capacity devices has led to something of a renaissance of gravity …
17.3 MINERAL PROCESSING AND BENEFICIATION PROCESSES. It is the first process that is done to separate useful minerals from the waste rock or gangue. This produces a more concentrated material for further processing. Concentrating the needed minerals in the mined material is known as the beneficiation process.

Intensive mineral processing steps are then carried out on the ore such as pre-concentration, beneficiation, or concentration to separate valuables from gangue. Once the valuables are recovered in the process plant, tailings management is a major step involving storage of tailings, water reclamation and detoxification of the mill and/or final ...
