Slag is the by-product of iron- and steelmaking processes. Normally, around half to one tonne of slag would be generated for yielding one tonne of rolled iron or steel (Lobato et al. 2015).It was reported that the world steel production was 1.9 billion tonnes in 2016, which suggested that at least around 1 billion tonnes of slag is produced during …

The majority of the waste material of the recycling process is ladle slag, or the slag that remains in the ladle after the casting process, and all the refractory material of the ladle after its ...

Slag is a mainly non-metallic by-product that is made up of silicates, alumina silicates, calcium aluminum silicates, and iron oxides (Joulazadeh and Joulazadeh, 2010). During the BOS process a proportion of the molten iron cannot be recovered so elemental iron is often observed in the slag (Yildirim and Prezzi, 2011).
