| A process for producing substantially dry slag granules comprises adding a controlled amount of water to a molten stream of slag, and granulating the slag to produce solidified slag comprising substantially dry slag granules and slag wool. An apparatus for producing substantially dry slag granules comprises: (a) an inclined surface having an upper and lower ends for receiving and discharging the stream of slag; (b) a dispersion device at the lower end of the inclined surface for dispersion of the molten slag; (c) one or more water addition devices for adding a controlled amount of water to the molten slag; and (d) a collection area adjacent to the dispersion device for deposition of solidified slag produced by the dispersion. The quantity of slag wool produced by the process and apparatus is less than that which would be produced without the addition of water. | ||||||

| 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. | ||||||

| An amount-reduction, harmless, disposal method for heavy metal waste gypsum (HMWG), which belongs to the technical fields of recycling economy and environmental protection. The HMWG used as raw material is subjected to processes of smelting fluxpreparation, lead smelting, fuming, and geopolymeric gelling, to realize amount-reduction, harmless and resources recycling utilization of heavy metal waste gypsum. The smoke containing sulfur dioxide produced in the smelting process is sent to the acid making system, and the produced dust with heavy metal is sent to the dedicated system for heavy mental disposing. The smoke dust produced in the fuming process is returned to the lead smelting system. The secondary HMWG produced in the acid making system would be returned to the preparation process of smelting flux. And the final products would be sulfuric acid and geopolymer material. | ||||||

| 166 | Method for processing slags of non-ferrous metallurgy | US14394697 | 2013-04-15 | US09435005B2 | 2016-09-06 | Maija-Leena Metsarinta; Jussi Liipo; Pekka Kurki; Madeleine Scheidema |
| A method for processing slags containing iron and non-ferrous metals, to produce clean slag free of detrimental substances and non-ferrous metals and suitable for use as a raw material or construction material. Slag is reduced in a reduction furnace with the help of reducing agents so that at least 5% of the iron of the slag is reduced into metal. Some of the non-ferrous metals, such as zinc, lead, arsenic and cadmium, vaporize. The contents of the reduction furnace are continuously mixed to prevent separation of a metallic phase from the slag. The generated slag-metal mixture is tapped off from the reduction furnace, cooled, crushed and ground to a finer size. Finally, a metal fraction is separated from a clean slag. | ||||||

| 172 | Preparation method for stainless steel slags and steelworks slags for recovery of metal | US13582966 | 2010-11-11 | US09212404B2 | 2015-12-15 | Carsten Gerold; Frank Dardemann; Joerg Langel; Holger Wulfert |
| The invention relates to a preparation method for stainless steel slags and modified steelworks slags for recovery of metal. In order to create a dry preparation method which guarantees a low wear and energy efficient comminution and de-agglomeration of stainless steel slags and modified steelworks slags as well as a selective separation of a metal fraction and a silicate fraction and which can be variable in relation to the different slag compositions and different requirements upon the quality of the metal fraction and the at least one silicate fraction, a roller mill is used at least for the comminution. The slags are supplied with a feed grain size of up to approximately 150 mm. The use of an air swept roller mill is advantageous, in which the comminution and de-agglomeration, if necessary drying, and at the same time a separation into an extensively mineral-free metal fraction and a virtually metal-free silicate fraction are brought together. When using an overflow roller mill the separation of the metal fraction and the silicate fraction takes place in an external classifier. | ||||||

| 174 | Device for recovering heat of molten slag | US13320080 | 2010-05-11 | US08764439B2 | 2014-07-01 | Tadaaki Shimizu |
| A device for recovering heat of molten slag, having a simple structure and high heat recovery efficiency. The device includes: a fluidized bed (3) formed of a fluidized bed material (32) composed of a crushed solidified slag; a slag pool (4) for feeding a molten slag to the fluidized bed; heat transfer tubes (7) for recovering heat from the fluidized bed; and a solidified slag withdrawing device (21) for recovering a solidified slag (34), such solidified slag (34) being formed in the fluidized bed as the molten slag is solidified therein. Molten slag droplets (31) are dripped into the fluidized bed (3) from the slag pool (4) and solidified in the corresponding fluidized bed. The heat released at that time is transferred to the heat transfer tubes (7) through the bed material (32). Further, heat-transfer coefficient between the heat transfer tubes and the bed material is about 10 times larger than that between the heat transfer tubes and gas, thereby reducing heat-transfer area for required heat recovery amount, thus making it possible to reduce the size of the heat recovery device. | ||||||

| The invention makes public an environment-friendly non-noise matte granulation technique. Melted matte flows out from the chute, then gas is sprayed on the matte through spray facilities; the gas disperses the melted matte into a large amount of tiny liquid drops, and cools the dispersed tiny drops to semi-melted or solid copper grains; in the following dropping course, the copper grains are quenched by pressurized cold water; finally, copper grains drop to the cold-water pond along with the pressurized cold water for further cooling, and the produced sand-like mattes are sent to the next procedure through dehydration-and-transportation system. It can overcome explosion and prevent chemical reaction in quenching, reduce noise pollution, and has the properties of simple procedure and easy operation to settle the problems existed in water quenching of matte. | ||||||
