Abstract: Disclosed is a direct reduction process for a metalliferous material which comprises supplying the metalliferous material, a solid carbonaceous material, an oxygen-containing gas, and a fluidising gas into a fluidised bed in a vessel and maintaining the fluidised bed in the vessel, at least partially reducing metalliferous material in the vessel, and discharging a product stream the comprises the at least partially reduced metalliferous material from the vessel, in which: a) the metalliferous material is reduced in a solid state in a metal-rich zone in the vessel; b) the oxygen-containing gas is injected above the supply of the metalliferous material into a carbon-rich zone in the vessel with a downward flow in a range of plus or minus 40 degrees to the vertical and heat by reactions between oxygen and the metalliferous material, the solid carbonaceous material and other oxidisable solids and gases I the fluidised bed is generated, and c) heat from the carbon-rich zone is transferred to the metal-rich zone by movement of solids within the vessel.

Abstract: An apparatus for reducing a metalliferous material in a fluidised bed comprises a vessel (3) for containing the fluidised bed, a means (5) for supplying the metalliferous material, a solid carbonaceous material, an oxygen-containing gas, and a fluidising gas into the vessel for forming the fluidised bed in the vessel. The oxygen-containing gas is supplied by one or more oxygen-containing gas injection lances (9) each having a lance tip (11) with an outlet that is positioned for injecting the oxygen-containing gas in a downward flow into the vessel within a range of plus or minus 40 degrees to the vertical. The lance includes a central pipe for the oxygen-containing gas and a passageway located outwardly of the central pipe for injection shrouding gas.

Abstract: A direct reduction process for a metalliferous material includes supplying a solid carbonaceous material and an oxygen-containing gas into a fluidized bed in a first vessel and generating heat by reactions between the oxygen-containing gas and the solid carbonaceous material and any other oxidizable solids and gases in the fluidized bed and discharging a hot off-gas stream containing entrained solids. The process also includes supplying the metalliferous material to a fluidized bed in a second vessel and supplying the hot off-gas stream containing entrained solids from the first vessel to the fluidized bed in the second vessel and partially reducing the metalliferous feed material in the solid state in the fluidized bed and discharging a product stream of partially reduced metalliferous material and an off-gas stream containing entrained solids.

Abstract: A direct reduction process for a metalliferous feed material, particularly for an iron-containing feed material, such as iron ore is disclosed. The process involves supplying the metalliferous material, a solid carbonaceous material, oxygen containing gas, and a fluidising gas into a fluidised bed in a vessel. The fluidised bed is maintained in the vessel, metalliferous material is partially reduced and then a product stream comprising the partially reduced metalliferous material is discharged from the vessel. The distinguishing feature in this process is that it involves a combination of a carbon rich zone (17) and the introduction of an oxygen containing gas in this zone which is then applied to cause agglomeration of the fine ore particles and thereby increase their retention time.
