    Abstract: A method and an apparatus method for producing direct reduced iron (DRI) from iron ore using biomass as a source of reductant and as a heating source of the iron ore and electromagnetic energy as a further heating source in a furnace having multiple zones. The zones include a preheat zone and a reduction zone between an inlet for briquettes of iron ore and biomass and an outlet for direct reduced iron. The method includes counter-current movement of (a) briquettes of iron ore and biomass in a direction from the inlet to the outlet and (b) combustible gases in an opposite direction in the furnace.

    Abstract: A method for producing direct reduced iron (“DRI”) from iron ore and biomass is disclosed. The method includes heating a batch of iron ore and biomass in each oven chamber of a non-recovery batch oven by a combination (i) the thermal mass of a lining of the oven chamber and (ii) combustion of a fuel gas from at least one other oven chamber and at least partially reducing the iron ore and forming DRI. The method also includes discharging gases from the oven chamber through passageways in a wall and a floor of the oven chamber and further combusting combustible gases and transferring heat to the wall and the floor of the oven chamber as the gases move through the passageways. The method also includes discharging at least a portion of gases from the oven chamber, without passing the gases through passageways in the floor of the oven chamber, and using these gases as a fuel gas in subsequent combustion heating in other batch oven chambers when a first predetermined trigger point is reached. A non-recovery batch oven is also disclosed.

    Abstract: A process and an apparatus for producing direct reduced iron (“DRI”) from iron ore and biomass are disclosed. The process includes heating a batch of iron ore and biomass in a batch oven (3) and reducing iron ore and forming a solid DRI product having a metallisation of 80-99% and generating an offgas. The process includes discharging the solid product at the end of the batch cycle and discharging offgas during the course of the batch cycle. The process operates the batch oven in a temperature range of 700-1100#C in a batch cycle time of 10-100 hours.

    Abstract: A smelting apparatus that includes (a) a smelting vessel (4) that is adapted to contain a bath of molten metal and slag and (b) a smelt cyclone (2) for pre-treating a metalliferous feed material positioned above and communicating directly with the smelting vessel The apparatus also includes an oft-gas duct (9) extending from the smelt, cyclone for discharging an off-gas from the smelt cyclone. The off-gas duct has an inlet section (18) that extends upwardly from the smelt cyclone and is formed to cause off-gas to undergo a substantial change of direction as it flows through the inlet section of the off-gas duct.

    Abstract: A process and apparatus for direct smelting metalliferous material is disclosed. The invention concentrates injection of solid feed materials comprising metalliferous material and carbonaceous material into a direct smelting vessel during the course of the process into a relatively small region within a metal layer in a molten bath in the vessel in order to generate a substantial upward movement of molten material and gas from the metal layer into a region in the vessel that is above the molten bath. In particular, the invention injects the solid food materials with sufficient momentum and/or velocity via an opposed pair of lances that are oriented within the vessel and arranged to form overlapping plumes of injected material in the molten bath.
