Native metal - Wikipedia

Native metals were prehistoric man''s only access to metal, since the process of extracting metals from their ores (smelting) is thought to have been discovered around 6500 BC. However, native metals could be found only in impractically small amounts, so while copper and iron were known well before the Copper Age and Iron Age , they did not have a large impact until smelting appeared.
