History Iron was likely originally discovered and extracted as a result of wood burning on top of iron containing ores The carbon within the wood would have reacted with the oxygen in the ore leaving behind a soft malleable iron metal Iron smelting and the use of iron to make tools and weapons began in Mesopotamia present day Iraq between 2700 and 3000 BCE
