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
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 .
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 ...
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 ...
