Oct 29, 2019  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 year (Worldsteel Association 2016).
