Capturing CO 2 by steel slag (SS) via mineralization is regarded to be an excellent choice due to the high basicity of the slag. In this paper, recent research on the steel slag-based carbon capture and storage (SS-CCS) by mineralization was summarized. ... The first step is the recovery of Ca/Mg from the SS by leaching, ... Direct gas-solid ...

Steel slag is used as a sintering fluxing agent in many enterprises of China. For example, in the sintering plant of the Shougang Group, 4% of steel slag is added into sintered ore per ton and in the Taiyuan sintering plant, 6% of steel slag is added, achieving better effects. After a long practice time, the main advantages include [47,48,49]: ①

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 …
