Based on the literature [2,3,4,5,6,7,8,9,10,11,12], each production process is characterized by different slag to steel output ratios: 250–300 kg of blast furnace slag per ton of pig iron produced, 120–180 kg of basic oxygen furnace and electric arc furnace slags per ton of steel produced, and 30–80 kg of ladle furnace slag per ton of ...
A major difference between the NFM slags and other more commonly used SCMs is the high iron content in these slags [15], thereby yielding a higher Fe/Si, Fe/Ca and Fe/Al ratio compared to conventional SCMs such as blast furnace slag or fly ash, which could have an impact on the phase assemblage of hydrated cements.Several Fe-forms of typical cement …
These findings corroborate the literature on SCMs, highlighting iron slag's role in improving concrete performance through reduced permeability, which is critical for structures exposed to moisture and aggressive environments. The implications include extended service …

Steel slag (SS) and Iron slag (IS) are two examples of industrial waste that have been used as a partial or total substitute for natural aggregate in the manufacturing of …
Iron and steel making slag are by products of the iron making and steelmaking processes. To date, these types of slag have been widely used in cement and as aggregate for civil works. The report presents an investigation of mechanical and durability properties of concrete by adding iron slag as replacement of sand in various percentages.
Lan et al. [54] hypothesized an approach for the separation of metallic copper values from the iron-rich slag utilizing enhanced gravitational forces. The effect of additives under the influence of enhanced gravitational field was investigated. ... Similarly, the literature on Cu slag flotation using bio-surfactants is very limited. Extensive ...
Linz-Donawitz (LD) slag, a by-product of steel manufacturing process, is rich in iron oxide, calcium oxide, silica, various macro, and micronutrients as well as varying degrees of heavy metals ...
Literature [23] showed that the cementitious activity of IOT was improved using mechanical grinding, and the IOT cement meets the requirements of 32.5 silicate cement. The authors analyzed the enhancement of steel slag cement systems by ultrafine iron tailings in a previous study. The enhancement of SS-cement systems by ultrafine IOT has been ...
Furthermore, highlighted the significant iron content in copper slag, emphasizing the possibility of recovering and recycling iron along with copper. It recovers copper as an iron-copper alloy and oxides in the final slag (Busolic et al., 2011). Moreover, studies have proposed various methods for iron recovery from copper slag.

Zinc-containing iron slag is generated during the removal of iron from the zinc sulfate solution in a zinc hydrometallurgical process. Iron slag, except for arsenic, contains many valuable metals such as zinc, iron, and indium (Kashyap et al., 2021). Zinc-containing iron slag is already on the hazardous solid waste list (Zhang, C. et al., 2020).
The stable hearth discharge is crucial for the operation of a blast furnace (BF). This study established a mathematical model for hearth discharge based on Bernoulli's principle, which considers the blast pressure, kinetic energy of molten iron and slag, gravitational potential energy, the pressure loss of molten iron and slag flowing through the deadman and taphole.
Steel slag can be directly used as sinter flux and iron smelting flux for the production of steel [6]. The pretreated. steel slag can be utilized directly for road construction (around 49.7% in the …
Metal slag is a ferrous slag, industrial waste, and by-product of the iron industry produced during iron processing in steel plants due to removing impurities from iron ore [19]. The molten slag is a secondary raw material, a sintered metal product quenched under high water jet pressure to produce GGBFS [20]. The slag goes through 80% to 90% of ...

II. LITERATURE REVIEW A comprehensive study of the potential health risks associated with the environmental applications ( e.g. fill, road base, landscaping ) of iron and steel making slag was performed using characterization data for 73 samples of slag collected from blast furnaces, basic oxygen furnaces and electric arc furnaces.
Slag formation is an essential part of the iron extraction process in the blast furnace. Slag is essentially a mixture of metal oxides and silicon dioxide; however, it can also contain metal sulfides and other elements. During the smelting operation, the limestone introduced as a 'flux' is critical to slag creation.
Jatropha oil (JO) is a non-edible vegetable oil and a potential renewable energy source.
