1 Introduction. The basic oxygen steelmaking (BOS) process produced over 70% of the global crude steel in 2018, [] generating 100 to 150 kg of slag ("BOS slag") for every tonne of crude steel produced. BOS slag, a product of hot metal element (e.g., Si, Mn, Fe, P) oxidation and flux (e.g., lime, dolomite) dissolution, plays a critical role in the production …

Hence, attention has now been focused on the use of steel scrap for the production of reinforced bars by the 20 rolling and mini steel mills.

Hence, BOF slag is considered as a suitable AW for CCS. The use of steel slag for CCS at steel mills have several advantages that include: Cost reduction by avoiding the need to set up a new carbon capture facility with the conventional methods like water or amine scrubbing, membrane filtration or cryogenic distillation (Sarperi et al. 2014).

2.1 Blast Furnace Slag (BFS): Physico-chemical Properties. Blast furnace slag (BFS) is a coproduct of the pig iron production and has been widely used in various applications for many decades. Two types of BFS are generated from steel plants: (1) air-cooled BFS and (2) granulated (crystallized) BFS.

The various solid wastes in the form of slags and sludges that are emerged from steel plants are blast furnace slag, blast furnace flue dust and sludge, Linz–Donawitz (LD) converter slag, LD sludge, LD dust, mill scale, mill sludge, acetylene sludge, etc. The solids and liquid wastes generated from a steel plant are shown in Table 1. The ...

In many rolling mills, 100 per cent of scrap steel is recycled for the production of iron bars used for civil construction. Scrap steel recycling results in the generation of <7 per cent and 7-15 per cent slag for iron and high carbon respectively. "The sector is also highly dependent on imported billets.
