Correction to: Journal of Sustainable Metallurgy

Figure 9 in the article as originally published was mistakenly replaced with the graphic for Figure S1 in the Supplementary Material. The authors have also made a correction to the measurement instrument reported in the original figure caption (replacing NEO instrument with ProtIR). The correct figure and caption are presented below.
