Regained metals from dissociation process can safely return to metallurgic industry, and slag can be used as an additive to road and construction materials. The utilization of municipal waste using this method does not cause the emission of foul odours and does not produce a harmful ash, which is something that normally takes place in an ...
Process bleed streams may contain antimony, arsenic or mercury. Large quantities of water are used for slag granulation, but the majority should be recycled. Solid wastes and sludges The smelter contributes a slag that is a dense silicate. Sludges that require disposal will result where neutralized process effluents produce a precipitate.
Steel slag processing solutions. When using commonly used slag processing methods, up to 50 of steel cannot be recovered from slag fines. Magsort can increase the profitability in steel slag processing by recovering and briquetting the steel currently wasted when the slag is used as road construction materials.
Slag often contains valuable metals that can still be recovered and utilized. When crushed and sized properly, slag can be sold and used as valuable material in many different ways, for example, as aggregates. However, since slag usually contains uncrushable objects, it is typically considered a challenging feed material for conventional jaw ...
III Slag Processing The effluent limitations to be achieved by July 1, 1977 are based upon the pollution reduction attainable using those treatment technologies as presently practiced by the average of the best plants in these categories, unless present technology is uniformly inadequate within a category.
Steelmaking slag is subjected to the following four process- es solidify and cooling of the hot molten slag, crushing and magnetic separation treatment of the slag to recover the metal iron,
Mar 11, 2015 Slag Remover is made of many mixed minerals by filtering, crushing and hot working, the main mineral composition is SiO2. As a new type of composite casting material in cleaning metal surface, it is used in covering liquid metal, deslagging, and purifying during the process of casting. Features-. a Rapidly gathered slag and debris in the ...
Slag is hard to mill using latest technology of milling systems. Our micronization system is able to mill up to 600 mesh using less power by dry milling.
Aug 14, 2013 Scaled-up laboratory tests have been carried out and a technology for processing phosphorus production slags to produce mineral fillers was developed on their basis. Conclusions on the applicability of pilot batches of white soot in tire and paint industries and carbonate-silicate fillers in construction industry and agriculture were obtained.
Apr 04, 2012 Ironmaking and steelmaking slags are inevitably generated as a by-product from ironmaking and steelmaking processes. Main components of the slags are CaO, SiO2, Al 2 O 3, MgO, and iron oxides, and the compositions of slags depend on the process.
Scaled-up laboratory tests have been carried out and a technology for processing phosphorus production slags to produce mineral fillers was developed on their basis. Conclusions on the...

Steel slag and old bank slags may undergo volumetric expansion in the presence of water. The risk of damaging expansion occurring when using steel slag produced in modern processes is minimised by a combination of careful production control and processing. Air-cooled blast furnace slag is non-expansive.
Mar 24, 2013 Slag splashing technology reduces the wear associated to thermal and chemical attack by slag and mechanical impact. The splashed layer on the refractory lining acts as a working lining layer in subsequent heatheats and hence protects the original refractory. ... The lance height has a marked effect on the slag splashing process since the lance ...
Applications. Slag processing equipments can supply crushing, magnetic separation, separation, grinding and other deep-processing. First isolated particles can be melted steel making, the rest of the coarse particles used as motorways gravel aggregate material, crushed into fine slag powder can be elected iron powder, the rest was used for cement and concrete admixtures

Steel slag is alkaline slag, with lower temperature, the viscosity increases sharply, the liquidity variation, it is one of the important factors affect the steel slag processing, According to the need for different liquidity of steel slag to choose the corresponding steel slag treatment technology.
Feb 23, 2011 The results indicated that the maximum spread diameter of the slag droplet is the key parameter for the impact process. The maximum spread can be presented as a function of the Reynolds number, Weber number, and contact angle. For molten slag particles, the results show that, the larger the particle, the higher the deposition probability.
