Figure 2. XRD patterns of (a) as-supplied EAFD, (b) CaO-treated EAFD (CaO-treatment: 5 hours at 1100°C in air, Ca:Fe
molar ratio =1.3), (c) NaOH, (d) KOH, (e) LiOH leaching residues (Leaching conditions: 2M solutions at 70°C for 2 hours,
1:300 S:L ratio), and (f) calcined residue (Calcination: 4 hours at 500°C in air)
