Die Erfindung betrifft ein Verfahren zur Herstellung eines Granulats aus Konverterschlacke bei dem gegen den Strahl einer aus- bzw. herabfließenden Konverterschlacke ein starker Luftstrom gerichtet wird. Dabei ist zur Herstellung eines dichten, raumbeständigen Granulats der Massestrom der Luft zum Massestrom der aus- bzw. herabfließenden Konverterschlacke so eingestellt, dass sich eine Fraktionierung in ein eisenreiches und in ein eisenarmes Granulat mit einer mittleren Dichte größer 1 kg/dm3 ergibt, das unter Ausnutzung des in der Konverterschlacke enthaltenen Eisenoxids einen niedrigen Gehalt an freiem Kalk aufweist, der den Anforderungen als Zuschlagstoff zur Herstellung von Beton oder Mörtel entspricht.

263 SPHERICAL HYDRAULIC SUBSTANCE AND PRODUCTION THEREOF EP91918995.1 1991-11-01 EP0513367A1 1992-11-19 HATTORI, Ken-ichi; ASAKURA, Etsuro, Mitsubishi Materials Corporation; FUKUTA, Yasuhiro, Mitsubishi Materials Corporation; FUJISAWA, Hiroyuki, Mitsubishi Materials Corp.

A spherical hydraulic substance comprising a hydraulic powder based on CaO, SiO₂, Al₂O₃ and Fe₂O₃, wherein at least the surface of the powder is melted for smoothening and then cooled and the powder has a particle diameter of 500 µm or less and a means circularity of 0.7 or above. This substance is produced either by melting the starting material mainly comprising the above oxides, followed by splashing to effect cooling for solidification, or melting at least the surface of the hydraulic substance, followed by cooling for solidification. Alternatively it is produced by mixing a hot substance such as iron making slag in a state molten or heated above 500°C with a dried, calcined, sintered or molten starting material based on at least one oxide selected among CaO, SiO₂, Al₂O₃ and Fe₂O₃ and splashing the molten mixture to effect cooling for solidification. Since this substance is a minute spherical particle having a smooth surface and a shape close to a true sphere, it is remarkably excellent in fluidity and strength when kneaded with water.

268 METHOD FOR RECOVERING CALCIUM-CONTAINING SOLID COMPONENT FROM STEELMAKING SLAG AND RECOVERED SOLID COMPONENT EP16768006.5 2016-03-16 EP3275848A1 2018-01-31 FUKUI, Yasushi; ASABA, Akihiro; MATSUO, Shoichi; YAMAMOTO, Masaya

The purpose of the present invention is to provide a method for recovering calcium-containing solid components from steelmaking slag, with which it is possible to easily increase the calcium recovery rate. With the method, steelmaking slag is immersed in an aqueous solution containing carbon dioxide, and calcium in the steelmaking slag is made to leach out into the aqueous solution. Next, the immersed steelmaking slag is removed from the aqueous solution, and, subsequently, the pH of the aqueous solution is increased. When solid components precipitated by doing so are recovered, it is possible to recover solid components containing 20 % or more by mass in terms of calcium atoms.

An aqueous solution containing 30 ppm or more of carbon dioxide is brought into contact with a steel-making slag to elute phosphorus and calcium contained in the steel-making slag into the aqueous solution. Subsequently, carbon dioxide is removed from the aqueous solution to precipitate a mixture comprising a phosphorus compound and a calcium compound. In this manner, a mixture comprising a phosphorus compound and a calcium compound and containing phosphorus in an amount of 1% by mass or more in terms of phosphorus atom content can be produced.

The invention relates to a method for processing slags of non-ferrous metallurgy,containingiron and valuable metals,to produce clean slagthatis free of detrimental substances and valuable metals and suitable as it isfor use as a raw material or construction material. Slag is reduced in a reduction furnace (18) with the help of reducing agents (19) so far that at least 5% of the iron ofthe slag is reduced into metal. At the same time, some of the valuable metals, such as zinc, lead, arsenic and cadmium, vaporize. The contents ofthe reduction furnace (18) arecontinuously mixedto prevent separation of a metallic phase from the slag. The generated slag-metal mixture (21) is tapped off from the reduction furnace (18), cooled, crushed and ground to a finer size. Finally, a metal fraction (26) is separated from a clean slag (25).

Disclosed herein is a method of reducing slag, including the steps of: examining the components of slag to be reduced, and setting a target composition ratio after reduction; determining the mixing ratio and input amount of a complex reducing agent of a plurality of reducing agents in accordance with the set target composition ratio to determine the complex reducing agent; and supplying the complex reducing agent into molten slag to reduce the slag. The method is advantageous in that the reduction efficiency of slag can be maximized, various kinds of reducing agents can be efficiently used, and the recovery amount of valuable metals can be increased, thus reducing cost.
