Beneficiation - Wikipedia

Examples of beneficiation processes include froth flotation and gravity separation. Other economic uses of the term are in use. 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.
