Here, the type and quantity of the mineral phases obtained when carbonation was done with and without the use of NiNP was assessed by QXRD. Results for CaO and MgO experiments are presented in Table 3.
This was demonstrated by the results regarding the obtained carbonate quantities, determined by QXRD and TGA, using pure CaO and MgO materials, as well as one of the two steelmaking slags tested (CC slag).
