The iron and steel industry is an energy-intensive sector, and large amounts of waste/ by-products are generated during the steelmaking process, such as CO2, metallurgical slag, and wastewater. Enhancing the development and deployment of treating waste from the steelmaking process will be environment friendly and resource-saving. Capturing CO2 by steel slag (SS) via mineralization is regarded

We looked specifically at ferrous slag, the leftover material from the smelting of iron and steel, in the Chicago-Gary area of Illinois and Indiana. Ferrous slag is currently underutilized. Although the construction industry does use some slag as an aggregate, most is simply discarded. However, slag could be used to treat acid soils or acid mine drainage. Doing so would both offset the cost of

01-01-2021 Steel slag has a great potential application in cement and concrete production, for the reason that steel slag contains hydraulic components, such as C 2 S and C 3 S. But f-CaO and f-MgO in steel slag will cause poor volume stability and RO phase with little hydration activity has relatively high content in steel slag [ [22] , [23] , [24] ].

Steel Slag Recovery For Iron
At the present, steel is produced in integrated steel plants using basic oxygen process (BOF) or in specialty steel plants (mini-mills) using an electric arc furnace (EAF). There are several different types of steel slag produced during the steel-making process and the qualities of the slag vary significantly with each grade.

Steel slag aggregates are fairly angular, roughly cubical pieces with a flat or elongated shape (as shown in Figure 2.13 [49]). They have a rough vesicular nature with many non-interconnected cells, which gives a greater surface area than smoother aggregates of equal volume. This feature provides an excellent bond with concrete binder.

Magnetic separation is an effective method to recover iron from steel slag. However, the ultra-fine tailings generated from steel slag become a new issue for utilization. The dry separation processes generates steel slag powder, which has hydration activity and can be used as cement filler. However, wet separation processes produce steel slag mud, which has lost its hydration activity and is
