Geography Dictionary: beneficiation

Concentrating the mineral content of an ore by ore-dressing, smelting and pelletizing. Beneficiation usually takes place close to the site of an ore body prior to its transportation to a manufacturing region; it is carried out in Liberia, for example, to save transport costs on Liberian iron ore.

 
Britannica Concise Encyclopedia: beneficiation

Treatment of raw material (such as pulverized ore) to improve physical or chemical properties in preparation for further processing. Beneficiation techniques include washing, sizing of particulates, and concentration (which involves the separation of valuable minerals from the other raw materials received from a grinding mill). In large-scale operations, various distinguishing properties of the minerals to be separated (e.g., magnetism, wettability, density) are exploited to concentrate the desirable components. Beneficiation also is used in the ceramics and clay industries. See also flotation; mining; mineral processing.

Wikipedia: beneficiation


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.

Based on this metaphor, the term has come to be used within an economic development and CSR (corporate social responsibility) context - to describe the proportion of the value derived from asset exploitation which stays 'in country' and benefits local communities.

For example, in the diamond industry, the beneficiation imperative argues that cutting and polishing processes within the diamond value-chain should be conducted in-country to maximise the local economic contribution.
