Jan 12, 2020· 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.
Mar 12, 2015· Minerals of iron ore and other contents Hematite (Fe2O3) contains 70% Fe. Hematite iron ore is very widespread. It is characterized by high Fe content and low content of harmful impurities. Magnetite (Fe3O4) is a compound of FeO*Fe2O3 (31% FeO in pure form) and contains 72.4% Fe. It has magnetic properties at lower temperatures (until 570°C).
