(72) MILLNER, Robert (AT) (73) PRIMETALS TECHNOLOGIES AUSTRIA GMBH, Turmstraße 44, 4031 Linz (AT) (74) S.C.P AKKUM, AKKUM & Associates, No. 1777, rue 6.261, Yaoundé 2, Auditorium Jean Paul II boulevard, Face Brigade de Gendarmerie, Mbankolo, B.P. 4966, YAOUNDE (CM). (57) The invention relates to a method for the reduction of a metal oxide-containing material (2), wherein a reducing gas which is obtained using ammonia NH3 is used. The reducing gas is supplied to a reduction reactor (2) containing the metal oxide-containing material, and a top gas is discharged from the reduction reactor. At least one sub-quantity of the top gas is used as components in the preparation of the reducing gas, optionally after the top gas is prepared. A device (1) for the reduction of the metal oxidecontaining material (3) comprises a reduction reactor (2), a top gas discharge line (4) for discharging top gas out of the reduction reactor (2), at least one supply line for an ammonia contribution (7), a preparation system (6) for preparing the reducing gas, at least one supply line for the ammonia contribution (7) leading into the preparation system, and a feed line (8) for feeding the reducing gas and/or a precursor of the reducing gas to the reduction reactor (2), wherein the top gas discharge line (5) leads into the preparation system (6).
