Slags coming from stainless steel (SS) and ferrochromium (FeCr) production generally contain between 1 and 10% Cr, mostly present in entrapped metallic particles (Fe–Cr alloys) and in spinel structures. To Steel slag is calciumsilicatic, with a CaO range of 38–48%, and it has a SiO 2 range of 11–20%. The Fe in steel slag is in the form of steel, FeO, and iron-bearing minerals. These components can be separated from the steel slag by magnetic separation for the sinter and blast furnace or may be used in steelmaking.Steel slag in China: Treatment, recycling, and management

Steel slag, a waste from steelmaking plant, has been proven to be good candidate resources for low-cost calcium-based CO 2 sorbent derivation. In this work, a cheap and sintering-resistance CaO-based sorbent (CaO (SS)) was prepared from low cost waste steel slag and was applied to enhance catalytic steam reforming of coke oven gas After BOF slag was oxidized at 1300 ℃ for 240 min and cooled in the furnace (1 ℃/min), the grade of magnetic slag obtained by magnetic separation had a grade of 40.26%, a recovery of 70.95%(PDF) Separation of Iron and Calcium from a BSSF Steelmaking Slag

Steel slag, a byproduct of the steel making process, has been adopted as a material to reduce non-point phosphorus (P) losses from agricultural land. Although substantial studies have been conducted on characterizing P removed by steel slag, few data are available on the removal of P under different conditions of P input, slag mass, Gradation: Steel slag can readily be processed to satisfy the AASHTO M 147 (8) gradation requirements for granular aggregates. Specific Gravity: Due to the relatively high specific gravity (3.2-3.6) of steel slag, steel slag aggregate can be expected to yield a higher density product compared with conventional mixes (2.5-2.7).Steel Slag User Guideline Granular Base User Guidelines
