Reprocessing Gold Tailings by Gravity Methods

Tailings originating from the gravity concentration of a gold ore containing about 14 g/t Au have been treated by various beneficiation methods. These tailings have been screened on the 147 and 74 micron sieves and the two coarsest fractions have been separated on shaking tables with unsatisfactory results, but the concentrates have been examined in polished sections for …

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.
