ABSTRACT OF THE DISCLOSURE: In order to effect a reduction to a desired, constant degree as exactly as possible and to achieve a low surplus of carbon, the reduction by a treatment with car- bonaceous reducing agents is effected in such a manner that fine-grained solids which contain higher metal oxides are calcined by a treatment at 800 to 1100°C with hot gases, in which the solids are suspended, the calcined solids are reduced at a temperature in the range from 800 to 1100°C to form low metal oxides in a stationary fluidized bed, which is supplied with carbonaceous reducing agents and oxygen-containing gases, and the carbonaceous reducing agents are supplied to the stationary fluidized bed at such a rate as to reduce the higher metal oxides to low metal oxides, to maintain the reduction temperature in the sta- tionary fluidized bed and to ensure that the discharged matter has the desired carbon content. The exhaust gas from the stationary fluidized bed is supplied as secondary gas to the calcining step, and fuel is supplied to the calcining step at such a rate that the total of the heat generated by the combustion of said fuel and of the heat supplied by the exhaust gas provides the heat which is required for the calcination.
