The hot gases (about 700~900 °C) produced by the combustion of water gas simultaneously heat and transport the iron ore powder to the gas-solid cyclone separator. Then, under the action of gravity, the heated iron ore powder (450~600 °C) falls into the fluidized magnetization bed. Consequently, the hematite is quickly reduced to magnetite by CO.

12/01/2020  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.
