Looking at the merits and associated benefits, some of the top steel-producing countries have adopted or upgraded with a recycling technique of steel slags from time to time for various applications (as shown in Fig. 3), such as for road construction, soil enrichment, cement production, etc. Notably, recycling steel slag for a particular …
Steel slag has been widely used as amendment and silicon fertilizer to alleviate the mobility and bioavailability of heavy metals in soil. The objective of this study was to evaluate the influence of particle size, composition, and application rate of slag on metal immobilization in acidic soil, metals uptake by rice and rice growth.
Abstract Fertilizers made of steelmaking slag are important inexpensive materials for recovering degraded paddy fields. The results of our previous works showed that essential Ca and Si elements were effectively supplied by the dicalcium silicate phase (C2S) while the glassy phase of the CaO–SiO2–FeO system served as an Fe source. In …
In agriculture, steel slag had been successfully used as producing fertilizer, material to neutralize acidic soils, and soil amendments to remedy heavy metal-contaminated soils (Annunziata et al., 2014; He et al., 2017; Matveeva et al., 2018; Wang and Cai, 2006; Wang et al., 2015; Wen et al., 2020).
Steel slag is the by-product during the separation of molten steel from impurities in the steel-making furnace. The basic oxygen furnace (BOF) slag, electric arc furnace (EAF) slag, and ladle furnace (LF) slag are three major types of SS produced in the steelmaking processes.As drawn in Fig. 2, BOF slag and EAF slag are both produced …
