A method and apparatus for sintering a mixture of finely divided ore and a solid reductant, preferably in agglomerated form, includes heating the mixture on a hearth (6) with radiant energy in the form of infra red radiation from an infra red source such as infra red lamps (4, 5) to a sufficient temperature to induce ignition of the reductant. The hearth (6) is formed by a moving perforated conveyor surface (2) in which the material to be sintered is disposed for heating by the lamps. Below the hearth is a duct (3) connected to a vacuum source for drawing air through the hearth and material thereon.
