Beneficiation. in mining, beneficiation is a variety of processes whereby extracted ore from mining is separated into mineral and gangue, the former suitable for further processing or direct use. based on this definition, the term has occasionally been used metaphorically for the economic development and corporate social responsibility to describe the proportion of the value derived from asset.
