Characterization of Iron III Oxyhydroxides in Hydrometalllurgical Residues
The characterization of iron iii oxyhydroxides arising from neutralization (removing dissolved iron and/or impurities), or precipitation in storage ponds, mine drainage and waste streams (oxidization of dissoved Fe ii) can prove difficult. The low solubility of iron iii inherently creates a high su...

| description | The characterization of iron iii oxyhydroxides arising from neutralization (removing dissolved iron and/or impurities), or precipitation in storage ponds, mine drainage and waste streams (oxidization of dissoved Fe ii) can prove difficult. The low solubility of iron iii inherently creates a high supersaturation environment favoring the formation of nanoscale, poorly crystalline, and metastable phases. These often have poor physical properties - controlling the properties of the residue - and contain high loadings of important adsorbed components. In this manuscript we provide examples of iron iii oxyhydroxide characterization from hydrometallurgical residues and more synthetic-based studies. We detail techniques to help delineate differences between poorly crystalline iron iii oxyhydroxides (2- and 6-line ferrihydrite, schwertmannite, akaganeite and goethite), and more combinational approaches for when admixed in heterogeneous residues. Generally, identification and even quantification can be achieved with a higher degree of confidence than by use of a single technique such as X-ray diffraction (XRD) |
