Smelting reduction of iron orecoal composite pellets has been carried out into liquid iron bath in an induction furnace at a temperature of 1723 ± 10 K with different Fe/C ratio.
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 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 BC.
