A method and apparatus for producing direct reduced iron from dry compacts composed of iron oxide and carbonaceous material by feeding compacts no more than two layers deep onto a hearth and removing all the volatiles and metallizing the compacts by exposing said compacts to a radiant heat source at a temperature of from about 2400.degree. to about 2600.degree. F. (1316.degree.-1427.degree. C.) for a total time period of about four to ten minutes and partially cooling the compacts while discharging them from the hearth.
