A method of smelting iron ore in which iron oxide and hot char are introduced into a primary reactor to reduce the iron oxide and thereby form a molten pool of elemental iron and iron oxide slag. A carbon containing substance, comprising fixed carbon and a hydrocarbon containing volatile matter, is introduced into a secondary reactor. The hydrocarbon containing volatile matter is partially oxidized within the secondary reactor to produce the hot char and a fuel gas comprising hydrocarbons, carbon monoxide, carbon dioxide, steam, and hydrogen with a CO2:CO molar ratio greater than about 0.25. The fuel gas is burned within the primary reactor so that a projected flame is produced and the projected flame is directed into the iron oxide slag of the molten pool.
