<p>In a method for the production of molten metal, oxygen, a reducing agent and iron reduced in a reduction reactor are introduced into a melt gasifier, the reducing agent is gasified with oxygen and the reduced iron is melted by the heat which occurs, the cupola gas being used as at least a fraction of the reduction gas. Reacted top gas is drawn off from the reduction reactor. For increased efficiency at least part of the heat energy of the top gas and/or of the fraction of the reduction gas which is provided for use as cooling gas and as excess gas to be utilized for the indirect heating of at least one further gas used in the method.</p>
