There is an error in Figure 7(a). The scale of right y-axis for iron recovery (pct) should be corrected as follows.

Fig. 7
figure 7

Recovery of iron from slag as a function of CaO content at 1773 K (1500 °C) (a) and the morphology of iron ingot separated from slag (b)

Therefore, the following should be corrected.

  1. 1)

    Abstract; line 11; about 90 pct → about 60 pct

  2. 2)

    Table II; 2nd column; iron recovery (7.8, 24.4, 90.0, 24.8) → iron recovery (5.2, 16.2, 60.0, 16.5)

  3. 3)

    after Figure 9, line 2; iron recovery (~90 pct) → iron recovery (~60 pct)

  4. 4)

    Conclusions; #2, line 7; about 90 pct → about 60 pct
