Ceramic filter media used in the dewatering of iron ore over operating periods of 3–5 years were characterised using XRD and SEM. X-ray analysis revealed the main chemical components in the samples to be aluminium oxide, i.e. the filter material, magnetite originating from the filtered slurry, and a calcium oxalate scale.
