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.

More Details· As the demand of iron ore is increasing, it is necessary to recover the resources from the lean grade iron ore or goethitic ores through beneficiation. The correlation of mineralogy and texture to engineering parameters such as strength, comminution efficiency, product size and liberation was attempted [2], [3], [4] .

More Details· Mineralogy of iron ore deposits, directly influencing the outcome of any beneficiation step, must be considered. X-ray diffraction (XRD) is an indispensable tool for fast, accurate and tailored mineralogical analyses. XRD can be used for the quantitative assessment of full mineralogical composition at every step of ore-to-metal process.
