In mining, beneficiation (occasionally spelled 'benefication') 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 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.

"In the two years he’s been the chief executive, Mr. Penny has become a proselytizer for what he likes to call 'beneficiation' — which is a fancy word for doing well while doing good. I heard him make a speech in Washington a few months ago, in which he repeatedly used the Botswana example and to a less extent Namibia, where De Beers has a number of similar programs, to show what socially responsible companies can accomplish in Africa. He went on to say that every company doing business in Africa needed to practice this kind of enlightened stewardship if it hoped to succeed over the long haul."
