The dissolution of CO 2 in the aqueous ammonium salt solution is the speed-control part of the Slag2PCC process (c.f., Equation 2). Results reported that 4–5 mm CO 2 bubbles dissolved when they rose ~1.6–1.9 m in an unmixed water column (Legendre and Zevenhoven, 2016, 2017).Recently, Zevenhoven et al. (2019) proposed that properly …

Since the composition of LF slag depends on the composition of added fluxes and alloys, its properties will vary accordingly. This is mainly due to the various conditions used for steel refining. Another factor that affects the properties of the LF slag is the weathering treatment that the slag undergoes upon its removal from the furnace.
