  Occurrence of Metals | Introduction to Chemistry

  Native metals were prehistoric man''s only access to metal. The process of extracting metals from their ores (called smelting) is thought to have been discovered around 6500 BC. However, these metals could be found only in relatively small amounts, so they could not be used extensively. So while copper and iron were known well before the Copper Age and Iron Age, they would not have a large ...
