 — Fine slag (FS) is an unavoidable by-product of coal gasification. FS, which is a simple heap of solid waste left in the open air, easily causes environmental pollution and has a low resource utilization rate, thereby restricting the development of energy-saving coal gasification technologies. The multiscale analysis of FS performed in this study …

 — 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 …

 — Annually more than 400 Mt of metallurgical slags are produced worldwide [1,2,3,4,5].From the annual Cu concentrate smelter production capacity, which is equal to around 21 Mt of copper metal in 2021, it can be estimated that more than 45 Mt of CUS were produced from primary sources assuming a slag to copper ratio of 2.2 [3, 4].Only …

 — During ironmaking as well as during steelmaking, significant amounts of slag are produced. Two decades ago, more than 13 million tonne (mt) of blast furnace slag and 4 mt of steelmaking slag per annum were produced in the USA alone. It is therefore not surprising that many attempts have been made to re-use iron and steelmaking slags.
