Slag significantly effects the quality and the properties of the steel. Proper slag formation is a crucial part in clean steelmaking as in the old proverb: "Take care of your slag, the steel will take care of itself". What is the Function of a Slag? Slag is essential: to cover and .
ed. Note that in this study, the term "steelmaking slag" refers to the slags from the steel making process using basic oxygen furnace. 2. Main Subject 2.1 History of fertilizer using steelmaking slag as a raw material and the fertilizer control law The use of steelmaking slag as a raw material for fertilizer began to spread mainly in Europe.
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 wi im a bum bum face so go suck a thing A large diversity of mechanical are used to separate magnetic .
Aug 01, 2015· Slag is a separate phase than liquid steel since (i) it is lighter than the liquid steel, and (ii) it is immiscible in the liquid steel. The important roles slag plays during steelmaking are as given below. It acts as a sink for impurities during refining of steel.
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,
Application of magnetic separation to steelmaking slags . The magnetic separation method is used for separating metallic iron and iron minerals from steel slag. Commonly used magnetic machines are the cross-belt magnetic separator, drum magnetic separator and magnetic pulley separator.
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 ...

Apr 04, 2012· Iron droplets are recovered by magnetic separation and remained slag is sold for various purposes such as civil engineering, cement or concrete resource. BF slag is completely recycled, while small fraction of steelmaking slag cannot be utilized due to the elution of hazardous elements such as heavy metals or fluorine.
ing slag has been estimated to be roughly equivalent to the total annual imports of P2O5 into Japan. 4) Hence, if it is pos-sible to separate P2O5 from slag, steelmaking slag will be an alternative resource of P2O5. The composition of steelmaking slag varies considerably according to the type of process, and the conditions in the workshops, for ...
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 .
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 [25]. Figure 5shows the annual utilization amount of steelmaking slag as fertilizer compared to the total production [2, 26 ...
If the strong magnetic field is applied to the crushed slag, precipitated calcium-phosphate solution phase can be separated from Fe t O matrix phase due to the large difference of each magnetic property. It has also been indicated by the Waste Input–Output model that the phosphorus recovery from steelmaking slag by the new process proposed in ...

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 .
Metal Recovery from Steelmaking Slag Qi Yu Master of Applied Science Materials Science and Engineering University of Toronto 2018 Abstract An experimental study was carried out to recover metal values from a steelmaking slag through air oxidation and magnetic separation. The oxidation of slag was carried out in both solid and
In this work, experiments were performed to determine the filterability of calcium carbonate produced with an alternative calcium carbonate production concept. The concept uses steelmaking slag as raw material and has potential to fix CO2 emissions and utilize steelmaking slag, simultaneously. As calcium carbonate is precipitated in a solution containing ammonium chloride, calcium chloride ...
