Improvement of the grade of ores by milling, flotation, sintering, gravity concentration, or other processes. Also termed "concentration".

crushing and separating ore into valuable substances or waste by any of a variety of techniques

The processing of ores to regulate the size of a desired product, remove unwanted constituents, and improve the quality, purity, or assay grade of a desired product. Concentration or other preparation of ore for smelting by drying, flotation, or magnetic separation.

It is the process of concentration of valuable components of an ore or any other mineral commodity. It commonly includes the multiple stages like crushing, grinding, washing, screening, flotation, roasting, etc.

a general term referring to any process that improves the quality of the coal after it is mined

The concentrating or enriching of the valuable minerals in an ore.

concentration from a larger mass of material. Methods employed to prepare a final marketable product from material as mined. Examples include screening, flotation, magnetic separation, leaching, washing, roasting etc.

The treatment of mined material, making it more concentrated or richer.

Beneficiation is a variety of processes whereby extracted ore from mining is reduced to particles that can be separated into mineral and waste, the former suitable for further processing or direct use.
