metallurgy: Concentration of the Ore | Infoplease

In certain cases (as when gold, silver, or occasionally copper occur free,, uncombined chemically in sand or rock), mechanical or ore dressing methods alone are sufficient to obtain relatively pure metal. Waste material is washed away or separated by screening and gravity; the concentrated ore is then treated by various chemical processes.
