Ancient Metallurgy
Although small amounts of metals are found in relatively pure form, most must be extracted from more complex ores by removing the impurities (non-metal or other metal) from the combination ore. It is possible, of course, to pound on metal ores and chip off pieces, and a few very early chipped stone tools were in fact made of chipped ore.

Gold panning is a simple process. Once a suitable placer deposit is located, some alluvial deposits are scooped into a pan, where they are then wetted and loosed from attached soils by soaking, fingering and aggressive agitation in water. This is called stratification; which helps dense materials, like gold, sink to the bottom of the pan.
