ABSTRACT:
A method of and apparatus for reducing an oxide of iron such as the oxides which occur in mill scale involves mixing particles of the oxide with particles of a carbonaceous reducing agent and passing the resulting mixing through a conduit disposed in the flue of a furnace, the flue gases which pass through the flue having a temperature sufficiently high to cause the reduction of the oxide by the reducing agent.
