Economic potential and environmental impact of metal recovery …
Nonetheless, the journey of CS does not end here. The path and evaluation of CS for metal recovery or storage as waste depends on two factors. First, the concentration of the metal to be recovered in the slag must be more than or equal to the concentration in the ore from which the slag is obtained (Guo et al., 2018).

Slag recycling
When the liquid (molten) slag is quenched with water in a granulation plant (Fig. 5), a glassy and granular product is created, which must subsequently be ground to produce a fine powder, which is used as a clinker substitute. Ground granulated blast furnace slag (GGBFS) has similar cement-like properties to Portland cement.
