The present invention provides a method for producing metallic iron, which is operable at low temperature. The present invention relates to a method for producing a metallic iron, which comprises heating and reducing a raw material mixture containing a carbonaceous reducing agent and an iron oxide-containing material to produce the metallic iron, wherein the carbonaceous reducing agent has a volatile content of 20 to 60 mass %, a gas derived from the carbonaceous reducing agent is a CO-CO 2 -H 2 gas, and the method comprises forming solid Fe 3 C by heating the raw material mixture in an atmosphere containing the CO-CO 2 -H 2 gas, melting the Fe 3 C, and carburizing a reduced iron through the molten Fe 3 C. |
