Abstract: The invention concerns a method for the preparation of fine-grain ore (2) in which the ore (2) is subjected to wind screening using a gas. Two fractions are formed (6, 8): a crude fraction (6) and a primary fine fraction (8), whereby the crude fraction (6) is ejected (6) and the primary fine fraction (8) is carried along by the gas, then deposited out of the gas and at least the majority thereof this is processed together with the crude fraction (6). The primary fine fraction is subjected again to a wind screening (8) using a gas which results in the deposition of a secondary fine fraction (18) and is processed together with the crude fraction (6). An ultrafine fraction (19) is carried along with the gas and then deposited out of the gas. In the subsequent processing steps which the fine grain ore (2) is subjected to, caking and sticking which can be caused by the ultra-fine fraction (19), can be avoided.

Abstract: The invention relates to a method of producing slurry-coated feed stock to be used for a direct reduction process. According to the inventive method, lumpy material that is constituted by iron-oxide containing pellets and/or iron-oxide lump ore is provided with a coating. The lumpy material is contacted with the slurries that arise in steel works, especially during the reduction process itself and/or during subsequent process steps, and is thereby coated with said slurries. The inventive method allows the production of coated lumpy material at low costs and prevents the iron sponge produced from the coated lumpy material from sticking during production. The inventive method allows a quantitative utilization of slurries that arise in steel works.

Abstract: The metallurgical-works dust is taken to a first furnace atmosphere, preferably at 1000 to 1100 °C. The dust pellet is kept with continuous agitation therein until especially chlorine, alkaline and lead compounds have virtually totally evaporated from the dust. Experience shows that this takes an hour. A stream of flushing gas is fed into the furnace atmosphere so that the lead-chlorine-alkaline vapour is taken from the rotary tube furnace to a condensation and filtering installation. Reducing agents, especially carbon, are then added to the metallurgical-works dust, which is taken to another hot furnace atmosphere, especially at 1150 to 1350 °C and continuously agitated therein. This reduces the zinc oxide in the dust, while the dust remains in the furnace until substantially all of the zinc has evaporated as metallic zinc vapour from the dust into the oxygene-containing furnace atmosphere and the metallic zinc has been converted into zinc oxide. Experience has shown that this takes up to two hours. Here, too, a stream of flushing gas is fed into the furnace atmosphere and takes the zinc oxide out of the furnace and the flushing gas with the zinc oxide is cooled and filtered.

Abstract: A process is shown where an arc dust waste produced by an electric arc furnace is conducted to silos and converted to a reusable co-product by means of the addition of a special blend of high calcium and dolomitic quicklime, calcium stearate and pulverized waste paper. A dolomitic quicklime is stored in a silo (11) and dispensed through a conveyance means, such as screw conveyor (13) to a weigh hopper (15). Kraft paper stock is withdrawn from a paper roll (17) and passed to a hammermill shredder (19) where it is pulverized down to the cellulose, longstock paper fiber. The shredded, pulverized paper passes through a blower (21) and through a conduit (23) to a paper cyclone (25). Paper stock from the cyclone (25) passes through an outlet duct (27) to the weigh hopper.

Abstract: Pellets of iron ore or other water insoluble particulate material are made from a mixture of the particulate material, moisture and a pelletising binder by forming moist green pellets, a water displacing additive is applied to the surface of these pellets after they are substantially wholly formed, and the pellets are then dried. The preferred water displacing additive is a solution of a silicone in an organic solvent.

Abstract: A method and an apparatus for operating a rotating apparatus, e.g. mixing drums or balling devices which comprise a rotating or reciprocating scraping device, e.g. in a balling drum (1). Said scraping device (6, 7) forms a periodically recurring pattern of scraping marks (8) in the particle layer (3) on the surface of the balling drum (1). The scraping device is frequently subjected to disturbing influences and may get into violent vibrations which may be accompanied by the formation of a vibration sustaining pattern superimposed on the periodically recurring pattern of scraping marks (8). Said disturbing effects can be eliminated by destroying the vibration sustaining pattern or simultaneously the vibration sustaining pattern and the periodicaly recurring scraping marks (8) pattern. An especially advantageous embodiment comprises changing the speed of the scraping device (6, 7) in an apparatus stated above with a rotating scraping device (6, 7) with intervals which are short enough to prevent that there is sufficient time for development of a vibration sustaining pattern in the periodically recurring scraping marks (8) pattern.
