Beneficiation is a variety of process 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 a context of economic development and corporate social responsibility 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.
