steelmaking slag magnet separate germany:of steelmaking slag was 3 470 000 tons for civil engineering 530 000 tons for cement production and 260 000 tons for subbase course material On the contrary the use of slag as a raw material for fertilizer or soil amendment still remains relatively small160 2000 tons for blast furnace slag and 100 000
Application of Magnetic Separation to Steelmaking Slags for Reclaimation Article in Waste Management 26(10):1133-9 · February 2006 with 437 Reads How we measure 'reads'
Weak magnetic separation. Weak magnetic separation is used to create cleaner iron-rich products that can be reused. These products have low levels of impurities and a high iron load. This technique is used as a recycling technology. It is coupled with steelmaking slag fines as well as a
Using the technology of weak magnetic separation coupled with selective particle size screening, steelmaking slag fines can be effectively separated to produce cleaner iron-rich products with sufficiently high iron contents and low levels of impurities to be reused.
The steelmaking slags are referred to by the steel production techniques used, such as BOF, EAF, and ladle furnace etc. These steel making slags typically contain 20–25% iron (Kawatra and Ripke, 2002).Because the chemical composition of steel slags is highly variable, the mineral composition of steel slag
Steelmaking Slag Beneficiation by Magnetic Separator and Impacts on Sinter Quality Ö. S. Bölükbaşı1, B. Tufan1* 1Department of Mining Engineering, Dokuz Eylül University, 35160, Izmir, Turkey Abstract: Basic oxygen furnaces (BOF) slag is the main problem at all iron and steel factories.
May 26, 2018· This evidence reveals the potential to separate P from steelmaking slag. In this chapter, various technologies for P separation and recovery from steelmaking slag are described. They include magnetic separation, capillary action, dissolution, and carbothermic reduction. Since each method has its own merits and demerits, the best choice of

Using the technology of weak magnetic separation coupled with selective particle size screening, steelmaking slag fines can be effectively separated to produce cleaner iron-rich products with
the molten slag to lower the viscosity and adjust the slag composition making it suitable for making glass ceramics. The liquid slag is air granulated and heat can be recovered. Component modification of steelmaking slag in an air quenching process to improve grindability was reported.
Request PDF on ResearchGate Separation and Recovery of Phosphorus from Steelmaking Slags with the Aid of Strong Magnetic Field In order to make sure the great potential of steelmaking slag as a new phosphorus resource, domestic phosphorus material flow in Japan including iron and steel industry has been investigated based on the statistical.
rization slag using a slag regenerator; P was reduced and concentrated in hot metal, and was further dephosphorized to produce fertilizer material. Yokoyama 5) proposed et al. a magnetic-separation method to separate and recycle the P-rich phase from steelmaking slag, by exploiting the dif-ferences in their magnetic properties.

As for the separation process, traditional methods such as magnetic field 9) flotation and reduction, have been studied, 10) but none of them can separate P-bearing phase from the steelmaking slag effectively.
Since 1981, steelmaking slag has been permitted for use as lime fertilizer, and now there are three standards (slag silicate, byproduct lime, and slag phosphate) that authorize the use of steelmaking slags as fertilizer . Figure 5shows the annual utilization amount of steelmaking slag as fertilizer compared to the total production [2, 26
