摘要： The invention relates to a conveyor belt to be used in a continuously operated conveyor-type thermal treatment, i.e. sintering, of a material bed. The conveyor belt is provided with perforations in order to allow the gases that are used for heating and possibly cooling the material bed to flow through the material bed and the conveyor belt. According to the invention, the conveyor belt is made of a perforated, at least one-part element (1, 11, 21) made of a metal piece and allowing the gases to flow through, said element being mechanically connected to the preceding and successive element (1, 11, 21) in the proceeding direction (5, 15, 28) of the conveyor belt by means of a junction made in the lateral direction of said conveyor belt, and the perforations (2, 13, 14, 26, 27) are arranged in zones alternating with perforation-free element pats.

摘要： This invention relates to a cascade-type scrubber, with which the wet scrubbing of the exhaust gas and removal of droplets from the gas can be performed in one and the same scrubber, producing a pure, dropless gas. It is thus essential that the cascade tubing typical of the cascade scrubber and the equipment for droplet removal are combined into a single compact entity, which is formed of several nested chambers.

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 and apparatus with which the aqueous solution from liquid-liquid extraction in the hydrometallurgical recovery of metals is purified from droplets of organic extraction solution. The aqueous solution is treated in a settling tank, where it is made to flow through a flow channel area with a reduced cross-section that extends over the width of the tank at least at one point. The flow channels are located in the lower section of the droplet coalescer according to the invention, with the upper section of the device being mainly solid.

摘要： In a method of charging fine-grained metals, in particular directly reduced iron (DRI), into an electric-arc furnace (1), the metal is supplied via a downpipe (12) to an opening (10) provided in the furnace roof (4), is introduced into the furnace (1) through this opening (10) as bulk material stream (11), and falls onto the melt (13) merely by grav ity. Further, an electric-arc furnace (1) suited for this purpose is described. A rather loss-free introduction even of fine-grained material having a mean grain size of less than 1 mm is achieved by passing the bulk material stream (11) through a dosing orifice (8) after the downpipe (12) and before entering the furnace (1). The bulk material stream (11 ) then enters the furnace essentially undisturbed.

摘要： The invention provides a flotation device including a series of flotation tanks (1) for processing a slurry incorporating valuable minerals for extraction. At least one of the tanks includes a side outlet (15) adapted for the withdrawal of targeted relatively fine coarse particles from the slurry. The tanks also include a bottom outlet (14) for the withdrawal of relatively dense or coarse components of the slurry. The incorporation of bottom and side outlets allows the slurry to be separated into two parallel streams, one configured for optimal recovery of the relatively coarse or dense slurry components and the other for optimal recovery of the relatively fine slurry components. In this way, outflow slurry from downstream tanks in the coarse particle stream has a higher proportion of coarser particles than was present in the inflow slurry from the upstream tanks. Consequently, when a flotation reagent is added to the slurry in the downstream tanks, there is a greater probability of coating some of the larger particles. Therefore, the probability of floating these larger particles increases in the downstream tanks. This in turn increases the overall efficiency of the flotation process.

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 centre 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.

摘要： The present invention relates to a process and a plant for producing sulfuric acid, in which a starting gas containing sulfur dioxide at least partly reacts with molecular oxygen in at least one contact with at least one contact stage to form sulfur trioxide, and in which the sulfur-trioxide-containing gas produced is introduced into an absorber and converted there to sulfuric acid. To achieve that only small gas volumes must be supplied to the first contact stage, based on the amount of sulfur dioxide used, with at least the same capacity of the plant and by using conventional catalysts, it is proposed in accordance with the invention to supply to the first contact stage a contact gas with a sulfur dioxide content of more than 16 vol-% and with a volumetric ratio of sulfur dioxide to oxygen of more than 2.67:1.

摘要： System (1) for the chemical/physical treatment of a fluid in which a distributor valve (3, 4) has been installed for the feed/discharge of fluid to/from various reactors (2). The distributor valve consists of a plate valve with stationary plate (18) and rotary plate (19). A cylindrical body provided with a number of axial bores (11, 12) that change into radial bores (13) and emerge in the wall of a stationary housing (24) adjoins the rotary plate and rotates therewith. A number of inlets/outlets (17) located one after the other viewed in the axial direction are provided on the stationary housing. According to the invention the various radial bores in the cylindrical body are provided with a fluid via axial bores, based on a single valve plate (19).
