Definition of BENEFICIATION
: the treatment of raw material (as iron ore) to improve physical or chemical properties especially in preparation for smelting
— ben·e·fi·ci·ate\-ˈfi-shē-ˌāt\transitive verb
First Known Use of 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 alsoflotation; mining; mineral processing.
