    摘要: A direct reduction process for a solid metalliferous material having a particle size distribution that at least in part contains micron sized particles includes 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 partially reduced metalliferous material from the vessel. The process includes (a) establishing and maintaining a carbon-rich zone within the fluidized bed; (b) passing metalliferous material, including metallized material (which term includes partially metallized material), through the carbon-rich zone; and (c) injecting the oxygen-containing gas into the carbon-rich zone and oxidizing metallized material, solid carbonaceous material and other oxidizable solids and gases and causing controlled agglomeration of particles.

    摘要: A direct reduction process for a metalliferous material includes 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 includes the partially reduced metalliferous material from the vessel. The process comprises (a) reducing the metalliferous material in a solid state in a metal-rich zone in the vessel; (b) injecting the oxygen-containing gas into a carbon-rich zone in the vessel with a downward flow in a range of ±40° to the vertical and generating heat by reactions between oxygen and the metalliferous material (including metallized material), the solid carbonaceous material and other oxidizable solids and gases in the fluidized bed, and (c) transferring heat from the carbon-rich zone to the metal-rich zone by movement of solids within the vessel. The metal-rich zone is formed in a lower section of the vessel and the carbon-rich zone is an intermediate section below an upper section of the vessel. Oxygen-containing gas is injected into a central region of the vessel.

    摘要: The invention relates to a method and apparatus with which an organic solution that is slightly soluble in water is scrubbed of aqueous entrainment and impurities. In particular, the organic solution may be the organic extraction solution of liquid-liquid extraction used in connection with the hydrometallurgical recovery of metals. The purpose is to perform the physical separation of water droplets and the chemical removal of impurities from the organic solution simultaneously. This occurs by routing the solution to be purified in the settling tank through at least one flow plate cassette of reduced cross-section.

    摘要: The invention relates to a method for settling the dispersion formed in the mixing unit of liquid-liquid extraction, for controlling solution flows and for creating pure solutions in the separation part. According to the method, the flow speed of the organic solution phase is adjusted to be clearly higher than the flow speed of the aqueous solution phase, in which case in order to prevent border flow turbulence caused by the speed difference of the solution phases, the water drop dispersion layer left in between the separating solutions is adjusted to extend as far as the discharge end of the separation part. In order to settle the solution phases, at the front end of the separation part there are arranged at least three spots where the dispersion and the already settled solutions are made to flow through a picket fence forming a restricted transversal surface, in which case the first restricted transversal surface turns the flow fed into the separation part to follow the longitudinal direction of the separation part, and the second picket fence in the flow direction forming a restricted transversal surface allows the settled aqueous solution phase to flow freely in the bottom part of the separation part. The invention also relates to an extraction apparatus according to the method.

    摘要: The invention relates to a method for recirculating the heavier solution from the separation part of liquid--liquid extraction to the mixing unit of the same extraction step, so that part of the recirculated solution is returned to the mixing unit from the overflow of the discharge end of the separation part. An essential feature of the invention is that the major part of the heavier solution recirculated into the mixing unit is obtained from the separation part proper, along the whole width thereof. The invention also relates to an apparatus based on said method, in which apparatus, in the bottom part of the settler (6) there is located a heavier solution collecting channel (13) extending over the whole width of the settler and being provided with suction pipes (15) which are oriented in an inclined fashion towards the solution to be collected from the channel.

    摘要: The invention relates to a device for distributing hot feed into the feeding silos of a metallurgical furnace. The device comprises an inlet pipe for receiving the feed from the outlet of a previous process stage. A batching pipe is fitted to the inlet pipe for distributing the feed alternately into the feeding silos through feeding hoppers that are arranged below the inlet pipe and the batching pipe on the periphery of a circle. The inlet pipe and the batching pipe are arranged for rotation with respect to the center axis of the inlet pipe, whereby the feed is directed alternately into each feeding hopper. The batching pipe is arranged between a protective shield, which is insulated from the environment in a gas-tight manner. The distributor of hot feed according to the invention is especially well-suited to feeding homogeneous and free-flowing material, such as preheated and pre-reduced ilmenite into the feeding and batching silos. The invention provides an environmentally safe way to feed the hot feed.
