Recovery of Manganese and Phosphorus from Dephosphorization Slag with Wet Magnetic Separation Yong-Soo Jeong, Kazuyo Matsubae-Yokoyama, Tetsuya Nagasaka Graduate School of Environmental Studies, Tohoku University, Sendai 980-8579, Japan Key words: dephosphorization slag, magnetic separation, phosphorus, manganese Abstract
the non-magnetic, non-iron bearing slag fines do not have an existing market demand and ... which can effectively separate the metallics and iron oxides at particle sizes that are finer than that of convectional dry magnetic separation technology. The ... Quantitative Determination of Metallic Iron Content in Steel-Making Slag ...
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.
Steelmaking in steel works, the residue flowing out contains iron, the second recycling uses crane to pour the liquid slag of slag ladle with layering onto the slag bed ( or slag pit ), spray a proper amount of water to make the high-temperature slag quench fragmentate and accelerate cooling, and then excavate and loading with loading machine ...
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 ...

The slag can also be used to create fibers used as an insulation material called slag wool. Basic slag. Basic slag is a co-product of steelmaking, and is typically produced either through the blast furnace - oxygen converter route or the electric arc furnace - ladle furnace route.
3. Steelmaking Slag Processing Technology The iron/steel slag processing flow is schematically shown in Fig. 2. Steelmaking slag is subjected to the following four process-es: ① solidify and cooling of the hot molten slag, ② crushing and magnetic separation treatment of the slag to recover the metal iron,
Magnetic Separation is the process of separating components of mixtures by using magnets to attract magnetic materials. The process that is used for magnetic separation detaches non-magnetic material with those who are magnetic. This technique is useful for not all, but few minerals such as ferromagnetic (materials strongly affected by magnetic fields) and paramagnetic (materials that are less ...
