Production of precipitated calcium carbonate (PCC) from steelmaking
Fig. 10 shows solution pH recordings of the carbonation experiments, while a SEM image of the precipitated calcium carbonate (rhombohedral calcite) is represented in Fig. 11. We can conclude that precipitated calcium carbonate (PCC) can be produced also from the currently used test slag using ammonium salts as solvents.
