Mineral processing - Concentration, Separation, Flotation: Concentration involves the separation of valuable minerals from the other raw materials received from the grinding mill. In large-scale operations this is accomplished by taking advantage of the different properties of the minerals to be separated. These properties can be colour (optical sorting), density (gravity separation), …

By referring to the tables "Minerals and Their Characteristics" (pages 332-339) it is seen that the perfect grade of a copper concentrate will be 63.3% when the copper is in the form of bornite, 79.8% when in the mineral chalcocite, and 34.6% when in the mineral chalcopyrite. A common association is that of chalcopyrite and galena.

It utilizes the natural propensity of minerals to dissolve in percolating water and produces a mineral-rich solution. Mineral leaching operations optimize this process through the use of chemical leaching solutions (lixiviants). Cyanide lixiviants in particular have been a standard way of processing gold for more than a century.
