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.
The present study presents the effect of pH reduction in iron ore slurry for an iron ore filtration process. A reduction on moisture content and increase on filters …
iron ore is expected to rise by more than 200 million tonne per year to meet the internal demand & export. This additional requirement of iron ore will need beneficiation of low grade ore/fines to get the major portion of increased demand. This paper deals in brief to use of available methodologies for beneficiation of iron ore in Indian context.
