Abstract: A direct reduction process for a solid metalliferous material having a particle size distribution that at least in part comprises micron sized particles, comprises supplying the metalliferous material, a solid carbonaceous material, an oxygen-containing gas, and a fluidizing gas into a fluidized bed in a vessel and maintaining the fluidized bed in the vessel, at least partially reducing metalliferous material in the vessel, and discharging a product stream that comprises the at least partially reduced metalliferous material from the vessel. The process is characterized by: (a) establishing and maintaining a carbon-rich zone within the fluidized bed; (b) passing metalliferous material, including metallised material (which term includes partially metallised material), through the carbon-rich zone; and (c) injecting the oxygen-containing gas into the carbon-rich zone and oxidizing metallised material, solid carbonaceous material and other oxidisable solids and gases and causing controlled agglomeration of particles.

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: The solids will first of all reach a first container under atmospheric pressure and then reach a second container of variable pressure, which is disposed thereunder, before they are introduced into the pressure vessel. The first and the second container each have a lower outlet passage and a movable shutter cooperating with the outlet passage. The outlet end of the outlet passage is disposed 20 to 400 mm above the shutter in the closed position, in the closed position the shutter forms the bottom of a chamber at least partly filled with solids. The chamber is connected with the outlet passage in a gastight way, and there is no gastightness between the chamber and the shutter. In the closed position, the shutter carries a solid bed, a vertical solid column having a height of at least 1 m is present in the outlet passage and in the container. In the closed position, seal gas is pressed into the chamber and into the solid column from the outside.
