(PDF) Utilisation of LD slag — An overview ResearchGate
LD slag contains many alkaline oxides, porous characteristic, large surface area, high density and easy for solid-liquid separation [2, [9] [10] [11]. LD slag can be used as an adsorbent to removeIn locations such as Eastern India, steel slag can be utilized as a soil neutralizer for severely acidic soils; its usage as a fertilizer is also well-established. When used as rail ballast, steel slag has a longer life and durability than natural aggregates, reducing maintenance expenses.Utilization of Steel Slag in Sustainable Construction

Production, characterisation, utilisation, and beneficial soil
The risk assessment of slag utilisation needs to focus on two aspects: heavy-metal content of slag and animal toxicity resulting from slag application to soil. Although the short-term application of slag fertiliser has minimal risk (Gwon et al., 2018), there is limited and inconclusive evidence to show the long-term risks of applying slag The use of metallurgical solid wastes such as steel slag, in agricultural activity, has become very important to contribute to reducing the accumulation of such wastes in the environment and to increase crop production. So, this chapter aims to emphasize the main aspects of the application of slags to soil chemical attributes as The Comprehensive Utilization of Steel Slag in Agricultural Soils
