Metal Profile: Iron Properties and Characteristics

Jan 12, 2020 · Iron was likely originally discovered and extracted as a result of wood burning on top of ironcontaining 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 (presentday Iraq) between 2700 and 3000 BCE.
